Description

The present invention relates to a machine for producing slide fasteners with two interconnected parts, namely a first part, the so-called sorting device, which the punched out and pressed closure members are supplied unsorted and these from one another separates, brings it into the correct position and then automatically the second device, namely the Aufpreßvorfichtung, fed through which the fastener tape and is held and the locking members detected and placed on the tape and be pressed on.

It is known that there are machines in which the previously punched out Closure members are fed in small quantities to a chute, which is a sufficient Width possesses so that the legs of the Verao final links, which with their protrusion on get caught on one or the other edge of the slide, between the walls of the Slide can slide. Furthermore, a downward corridor is of sufficient abas measurements provided to enable the passage of the body of the closure member; this passage has a longitudinal groove for the passage of the projections over its entire length and opens on the upper edge the slide; in this passage all locking members can penetrate, their projection is on the side where the corresponding slide opens, with all others Closing members are eliminated. Because of this, the performance is well known Machines of this kind are necessarily very small.

By the machine for the production of zippers according to the invention, which one Slide and two downward-facing passages that open onto the upper edge of the slide possesses, which are each provided with a feed pipe of a corresponding internal cross-section this disadvantage is remedied; characterizes the machine according to the invention on the one hand by the fact that one passage is in one and the second in the other Side wall of the chute is located, and on the other hand, in that one of the feed pipes is rotated around itself by 180 °, around the projections of the locking members contained therein in the same direction as that

of the links contained in the other feed pipe achieves that the machine initially uses all previously punched out "locking links, which practically at a traveling speed which is the same as that of the locking members on the slide, to a Performance that is twice as large as that of the known machines, to The invention also relates to a device that has the purpose of the Feed pipes to eject the few interlocking links that head after them in them migrate down and therefore cannot be pressed onto the fabric when using the press-on device are fed in this position.

On the other hand, the ejector device should each wandering closure member in the feeder tubes always attack in the same position; but because of the tolerance in manufacturing, that would not be achieved by the superposition of a significant number of locking members the upper one Closure member always adjusts strictly exactly with respect to the ejector that would then no longer work safely and lead to jamming and thus to a blockage could give rise to the machine. By means of the invention, this drawback is by means of an automatic release device that comes into operation when the feed pipe is filled which is arranged in the vicinity and below the ejector device in such a way that it can fill the feeder tubes interrupts before the fastener link layers up to the level of the ejector have arrived.

The closure members can be used in the lower part of each feed tube does not take place, because the number of closure members that these tubes in a predetermined Time filling is not the same for every tube; according to the invention, the closure members of the two feed tubes come, fed a middle gear, which is appropriately against undesirable Shocks is protected and through which the locking members of the press-on device, are supplied immediately and in a suitable position. There are further means are provided by which it is possible, the lower end of each Feed pipe alternating with the upper end of the middle aisle in correspondence to bring while a device for holding the locking members in place allows this movement without the danger of a wandering Closure member is clamped. At the lower end of the middle aisle, the Closing members separated from one another by a dispensing device designed as a slide, through which the lower closure member is lent from the one immediately above it Closure member is separated and at the same time the head of the just put on Closing member depressed in such a way that the speed of pressing the closure member is increased on the fabric and the correct attachment of the fastener member is ensured on the fabric.

The locking links that lead to the end of the middle aisle with a relatively considerable speed increased by the slide, must necessarily be brought to the material on which it is pressed should be; for this purpose, the jaws of the fabric pliers when closed a guide passage for the projection of the closure member, while the jaws of the Aufpreßzange a guide passage for the body of the closure member in the same state form. '

The invention also relates, on the one hand, to a semi-automatic device for taking along the tape, which is intermittently by this device around a Amount is shifted, which corresponds to the gap between two successive closure members, and on the other hand on a device serving to disengage the press-on machine, by means of which it is possible to produce pressed-on tapes of predetermined and to obtain practically unlimited lengths, while the press-on machines used so far practically only lengths to be carried out that barely exceed 80 cm.

Finally, the invention also relates to a completely automatic device for Take the fabric band with you and an also automatic device for disengagement the pressing device with a totalizer in connection with a device, through which the number of locking members to be pressed on on the counter again formed, the empty end of the fabric tape pulled and the machine automatically is restarted.

All of these arrangements have the purpose of making all of them usable by the dispenser To enable supplied closure members without the work of the latter Device to delay somehow, whose performance, as already said, approximate is twice as large as that of the known machines.

The sorting and pressing machine shown in the drawings for the production of flexible metal fasteners

consists essentially of two parts firmly connected to a common frame, in fact: *

i. ' the sorting machine, which separates the unsorted connecting links, exposes, sorts, arranges, distributes and automatically prepares for placing and pressing onto the fabric, and

ίο 2. the press-on machine, which automatically attaches the connecting links coming from the sorting machine to the tissue and press on; This machine also includes devices for setting the feeding and pressing of the connecting links onto the tissue accordingly the length of the flexible metal fastener that one wishes to obtain. Every machine itself consists of a certain number of parts through which the the above-mentioned operations can be carried out. <-

i. The sorting machine consists of the following parts:

a) a separating device A, to which the connecting links are fed unsorted and which distributes them;

b) a sorting device!? which ^{arranges the 1} connecting links in the vertical and in the lateral direction;

c) a vibrating device C, which actuates the sorting device and guides the connecting links by gravity to the feed pipes E ₁ B ' ;

d) an ejector device D which ejects the links that have passed through the machine in the wrong direction;

e) an automatic interruption device F which starts when the feed pipes are completely filled ;

f) a device G, by means of which any feed pipe can be brought into connection with a middle gangue;

g) the middle course H of the expanding machine;

h) a cutting hammer m, 2. The press-on machine consists of the following parts:

a) a horizontal guide passage I for the flexible strip;

b) a distributor O which distributes the connecting links on the fabric;

c) a pair of forceps with two legs /, through which the tissue in the for receiving the Connecting links is held in a suitable position;

d) a crimping pliers K with two legs, through which the connecting links are placed astride the fabric edge and pressed on;

e) a semi-automatic device L for advancing the tissue;

f) an automatic device M for interrupting the pressing-on process and for adjusting the length;

g) an automatic device for advancing the flexible strip and for adjusting the length, for pulling the remaining length and for starting up.

The individual components of these two parts should be described separately; likewise the working of the same becomes simultaneous with the working of the with it cooperating parts explained.

The closure member Z, which is shown in elevation and side view in Figs. 1 and 2, is the common connecting member used in the manufacture of flexible slide fasteners. It has a projection ζ on one side and a corresponding depression z ' and two legs /' for pressing it onto the tissue on the opposite side.

i. The sorting machine a. The separator

The separating device A (Figs. 4, 4a, 5, 6 and 7) consists of a container 1 of suitable design, at the lower part of which the beveled end 101 of an inverted funnel 102 firmly connected to the cover 103 of the partial device 2 opens. This frustoconical part device 2, which receives its movement from the disk 104, has inside a drum 105 firmly connected to the cover 103 and penetrated by the funnel 102, while the outer circumference of the cone 2 has a number of openings 106, in the present case four, which are arranged in the vicinity of the lid 103. The latter carries internally through angle tabs 107 wings 108, in the present case four, the upper part of which is parallel to the cover and forms sections of a ring, the width of which corresponds to the distance between the cylindrical wall of the drum 105 and the inner wall of the frustoconical space 2, with which the side surface of this wing is flush. A free space 109 is provided between two consecutive wings 108. These wings form with the circumference of the drum 105 the inner wall of the space 2 and with the lid 103 the container with the feed openings 106, the bottom of which, which is formed by the part 110 which connects the wings with the fastening tabs 107, is approximately in the height of the openings 106 provided in the wall of the frustoconical space 2.

These openings 106 are opposite one Channel 3, the lower end of which opens above the sorting machine.

The connecting links lying unsorted in the container 1 get into the funnel 102 during the rotation of the part 2 and as a result of the bevel 101, from which they slide down under their own weight into the part device 2, the frustoconical shape of which moves the aforementioned links to the left (Fig. 7) drives. Here these members are grasped by the wings 108 and brought by these into the corresponding containers, on the lower part of which the openings 106 are located. The connecting links regularly fall through these openings into the channel 3, through which they are fed to the sorting device.
It should be noted that the dividing device 2 can also be provided by a similarly acting device, such as, for. B. a vibrating sieve, could be replaced.

b. The sorting device

The sorting device B (Fig. 4, 4a, 5 and 6) consists of two parallel shields 4 and 4 'with inclined funnel-shaped walls 113. The above-mentioned shields are connected to one another and held in place by form struts that have a gap between the shields that serves as a guide Leave 112 blank of carefully measured width. The shields are also provided with incisions 6, 6 '(Fig. 6) of special design, the dimensions of which correspond to the dimensions of the projection 2 of the connecting links Z. The shields are arranged within an inclined housing 8 designed as a scrap box. Through an opening 7 provided at the end of the channel, the channel is connected to said box 8, at the end of which a reject pipe 10 is provided.

The sorting device thus constructed is

♦ 5 with its rear part between two studs 5 pivotably mounted; it is connected to a vibrating device C at the front. The incisions 6 and 6 '(Fig. 4a) are followed by grooves 386, 386', which allow the passage of the projections ζ ; these grooves have a sudden change in direction 387, 387 'and then an essentially perpendicular part 388, 388', which is followed by a part with a smaller inclination 389, 389 '. The groove of each aisle is appropriately curved at 387, 387 'to allow the links to advance at a distance from the top of the guide less than the height of the portion of the links which is within the guides during their displacement . As a result of this arrangement, the legs of the connecting members, the projections of which are opposite the groove in front of which they are guided, are always guided through a full-walled part of the guide wall, so that there is no risk of them jamming in the groove. The grooves continue through an essentially vertical part 390, 390 ', which leads to the directional curvature 391, 391', and finally have a last part 392, 392 'which is arranged essentially perpendicularly. The struts 111 are arranged so that between their end faces they lead an aisle 393) 393 'to the aisles E, E'. is intended to interact with the directional curvatures 391, 391 'of the guide groove 386, 386' of the projections ζ . These courses 393, 393 'lead to the courses E, E'. These are flat and their width and thickness are dimensioned so that they allow a good layering and an appropriate guidance of the connecting links. They have an eccentrically arranged longitudinal groove e, e ', which is provided in one of the longitudinal walls of the aisles and corresponds to the groove 386, 386' of the sorting device; the width of these individual grooves intended for receiving the projection ζ of the connecting links Z is dimensioned accordingly in order to enable the said links to be guided perfectly.

c. The vibrator _g5

The vibrating device C (Fig. 4, S and 6) of a known type consists of a polarized magnetic relay, which is designed according to a principle similar to certain magnetic bell devices.

Incidentally, it should be noted that this vibrator is also replaced by another equivalent device, such as. B. a purely mechanical or pneumatic device, could be replaced.

The vibrating device C transmits to the shields 4 and 4 'swinging around the studs 5 a series of vibrations of suitable magnitude, by means of which the connecting links coming from the channel 3 are brought to the lower part of the guide. Because of the inclination of the walls 113, these connecting members get with their legs into the guide 112 and remain suspended there by their projection s , which prevents the same from penetrating between the shields 4 and 4 '. The connecting links therefore lie in the guide along which they slide forward, the projection of the individual connecting links either to the right or to the left

is tet. The four binding members, the projection is directed to the left, reach into the incision and during Auftrefien to the same, while the others continue their movement impinge on the ^v incision 6 to them and penetrate therein.

The defective links, for example with excessively large protrusions, as well the links arriving at the entrance of the incisions 6 and 6 'ίο in an incorrect position fall in the front part of the housing into - the opening 7 provided for this purpose, which opens into the reject pipe which leads to "a suitable container, not shown leads. The locking members with too small projections fall through the slot 112 even before they get to the incisions 6, 6 '. The connecting links thus eliminated are fed back into the machine until only the unusable ones and the rejects are eliminated.

The connecting links that have entered the incisions 6 and 6 'meet the sudden change of direction 387, 387' with their projection, whereby they are given a slight impact, by means of which they are to be brought into the vertical position as far as possible. The arrangement of the projection corresponding to the points 387, 387 'also has the purpose of guiding the legs of the connecting members, the projection of which is on the opposite side of the respective incision, so that these connecting members are prevented from partially penetrating into said incision, which is a Would cause disruption in the feed. The links, which are further guided by sliding their projection s in the vertical part 388,388 ', quickly leave this part of the sorting device to allow the free passage of the following links, and move along the slightly inclined point 389,389' so that they both under the influence of gravity and by the vibrations which the vibrating device communicates to them, should assume an essentially vertical position with the legs pointing downwards. Their movement is accelerated by 'the almost perpendicular part-390, 390'.

When a connecting link arrives in an almost vertical position, with the legs directed either downwards or exceptionally upwards, it moves on without being influenced by the directional curvatures and enters the feed pipe E, Έ in the normal way. If the connecting member arrives in an inclined position, in that it is supported by its projection against the directional curvatures 391,391 ', and in that the ends of the legs rest against the directional curvatures 9 and 9' of the struts ι π, so is its projection Pivoted far until the end of the legs is opposite to the vertical part of the aisle 393, 393 ', to which the feed aisles E, E' are connected. The connecting member thus comes into this in a vertical position, with the legs being directed downwards or upwards.

The supply tubes E ₁ E ' receive the connecting links immediately after they exit the sorting device, the projection ζ of the same penetrating into the groove e, e' of the corresponding ₄ aisle. The groove e, e 'of these supply aisles is expediently offset with respect to the center line of the wall on which it is located; This arrangement (Fig. 8) gives the connecting links Z an inclination which enables them to be guided appropriately without the risk of getting stuck. The arrangement of the grooves in the center line of the aisle sides, on the other hand, has the disadvantage that the connecting links often get stuck together (Fig. 9).

The connecting links therefore move in these pipes under the influence of gravity; they are arranged (Fig. 8) with their legs pointing either upwards or downwards, and they are guided by the sliding of their projection in the groove e or e '. One feed tube, namely E ' in the drawing, makes a half turn around itself, so that all connecting links have their projection on the same side when they enter the ejector device D.

d. The ejector

The ejection device Ό (Fig. 4, 5, 10, 11, 12, 13, 14, 15, 16 and 17) consists essentially of two levers 12 and 13, which are under the influence of the springs 116,116 'and around one with the Frame 11 firmly connected axis 115 swing. These levers are operated by lifting disks 17 and 18, which sit on a cord pulley ig. This is connected to the main motor that drives the sorting machine. The lever 12 (Figs. 10 and 11), the upper end 117 of which is supported against the lifting disk 18 and is held against it by the spring 116, which spring is attached on the one hand to the frame 11 and on the other hand to a projection 12 'of the lever 12 , has at the other end two punches 118, 118 'arranged at a suitable distance from one another. The lever 12 carries over the rams 118, 118 'resilient braking pieces 114, 114' which penetrate into the groove end 'of the gears E, E' , whereby the connecting links Z are prevented from being removed from the tip

the punch ii8, 118 'rebound. At the lower part of the lever 12 a bracket 12 ″ is provided, which serves to carry the lever of the automatic interruption device F , by means of which the disengagement is effected in the case of completely filled pipes and which will be described below. The lever 13 (Fig. 12 and 13) is under the influence of a spring 116 'which has one end

ίο on the frame 11 and with the other end a projection 13 'of the lever 13 is attached. This lever stands with its upper one The end 119 is in contact with the cam disk 17 and has two sets of punches 120 at the bottom, I2o 'and 121, 121'; the stamps 121 and 121 ', which are semicircular in development slide in channels 122, 122 'of the same Cross-section whose longitudinal center line is formed by a circular line whose center point lies on the geometric axis 115. These punches are influenced by springs 123,123 'which are arranged in the channels 122,122' are. The lever 13 carries a reset part 125 with two screws 124, which is shown in FIG Figs. 5, 14 and. 15 is shown and the purpose of which will be given below.

Each feed course E, E ' has a window 14, 14' on its side opposite the side provided with the groove e, e ' and at the level of the stamps 119, 120 of the levers 12 and 13, which is provided with a flap 15, 15' is locked. The flap 15, 15 'is firmly connected to two flanges 126 which carry a beak 127 and are rotatably mounted about an axis 133 (see FIGS. 16 and 17). Each flap 15, 15 'has a window 132, 132' at the level of the stamp 120, 120 '. Two springs r28, 128 'attached to frame 11 at 131, 131' each have a curvature 129 at one end which merges into a tail 130. Each of these springs acts on the beak pieces 127 of the flaps 15, 15 ', sometimes with their curvature 129 and sometimes with their tail 130.

A funnel 16 arranged under the windows 14, 14 'serves to receive the separated connecting links.
The operation of the ejector D is as follows.

When the lever 12 actuated by the lifting disk 18 is in the front position shown in FIGS. 14 and 15, it holds each of the rows of connecting links to be sifted or sorted in the feed aisles E and E by means of its punches 118, 118 '' firmly. These punches 118, 118 'can hold the series of links in such a way that either because of

«O the eccentric arrangement of the guide groove e, e 'of the gears E, E' only one leg of the first link is supported when it is in the correct position, or that the head of the link is supported against the punch when it, upside down as shown in the drawings.

This link Z (Fig. 14) is opposite the one through the flap 15 or 15 'closed window 14 or 14 '.

The actuated by the eccentric disk 17 lever 13 then tilts to the right about the axis 115 ^to - and takes the retraction member 125 with. During this movement, the punches 121, 121 ', which usually protrude beyond the punches 120, 120', work in such a way that they retain the link located immediately above the link Z being treated, either by being placed between the The legs of the same grip, as shown in Figs. 14 and 15, when it is in the correct position, or by the fact that the head of the connecting link is supported. During the further movement of the lever 13, the springs 123, 123 'are compressed by the punches 121, I2i' which abut against the floor of the passage E ₁ E ' , so that the punches 120, 120' can continue on their way. If the connecting member Z is in the correct position, the stamp engages between the two legs without coming into contact with the connecting member and exits through the window 132 provided in the flap 15, 15 '. On the other hand, if the connecting link Z is upside down (Fig. 14), the end of the corresponding die 120 or 120 'strikes against the projection ζ of the connecting link and, through its intermediary, pushes the flap 15, 15' back around the axis 133 swings out; after this movement has started, the tip 127 of the flanges 126, which was previously supported against the inclination 129 of the spring 128, is in contact with the tail 130 of the latter, whereby it continues its movement, so that the link Z into the Channel 16 can fall leading to the scrap box. The lever 1.3 then swings back in the opposite direction and thereby takes the retraction member 120 with it, which brings the flap 15, 15 'back into the original position in which it is held by the inclination 129 of the spring 128. The plunger 120, 120 'has completely exposed the passage E, E' , and the plunger 121, 121 'pushed forward by the spring 123 has remained in contact with the floor of the passage. The lever 13 then remains immobile and the lever 12 in turn swings backwards

from, whereby 'he pushes the punch ri8, 118' back, which has the consequence that the connecting link Z then escapes into the lower part of the feed aisle, provided that it was in the correct position and not through the punch 120, 120 ' was ejected. The lever 12 swings forward again in the direction of the gears and penetrates into the groove e, e ' . The lever 13 then continues its oscillation backwards anew, taking with it the punch 121, 121 'which releases the row of connecting links. The cycle then begins again in the manner already described.

It should be noted that the stamps 118, 118 'and 120, 120' expediently under the Influence of feathers, which they put into the state, in the case of an accidental Shutting down the device in such a way as to give way to damage to the device is avoided.

. e. Automatic shutdown when fully filled

The device F (see FIGS. 5, 18, 19 and 20), which is used to automatically stop when it is completely full, consists essentially of a lever 134 which is designed as a shovel; the front of this blade is curved and bent over in such a way that a bracket 135 is formed which has bores 136 for the passage of an axis 137 carried by the bracket '12 "of the lever 12 ^ (see Fig, s). The two walls of this bracket are continued by two shields «141 ', 141' which are provided with angled parts 142, 142 'on which the lower ends of springs 143, 143' are fastened by screws 149, 149 ' Springs press through their upper end on the angular edge 139 of a part 138, which has two beak pieces 138 ', 138 "and swings about an axis 140 firmly connected to the' corresponding shield. The shields 141, J41 'are arranged at such a distance from one another that the spout pieces 138', 138 "are at the level of the grooves e, e 'which are provided in the aisles E, E' , which are also on the walls which ^: face the walls "provided with the grooves e, e ' , have openings e _t , e / of appropriate width, which are intended to' ^{allow the passage of the beak"pieces;} i38 ', 138 "of the oscillating parts 138 to enable. Likewise, the distance between the two spout pieces 138 ', 138 "from one another corresponds to the distance between two projections on two successive connecting links in one and the same row is firmly connected to the lever 12; in the other direction the shovel lifts a bolt 144 made of insulating material To push blade 134. The sleeve 151 slides in a sleeve firmly connected to a power supply terminal 146 and at the end of the stroke comes into contact with the end part of a power take-off terminal 147. The whole is arranged in a block 150 made of insulating material and firmly connected to the lever 12.

When the lever 12 is in its rearward retracted position, the vibrating part 138 held in place by the pressure exerted by the upper The end of the flat spring 143 exerts on the angular edge 139 of said part 138. if the lever 12 reaches its extreme front position, so the following two can Cases occur:

a) the feed path E, E ' corresponding to the respective oscillating part 138 is not filled (see Fig. 19). In this case, only one of the two beak pieces, here the beak 138 ″, hits the projection ζ of a connecting link Z; the part 1 ^ 8 then swings about its axis 1.40 and lifts the spring 143 without changing the position of the shields 141, 141 ';

bj or the feed path E, E ' corresponding to the respective oscillating part 138 is full (see Fig. 20). In this case, the two 'beak pieces 138', 138 "of the part 138 are locked in that they abut against the projections S ₁ , g ₂ belonging to two successive links Z ₁ , Z ₂ , so that the part 138 about the axis 140. Under these circumstances, the lever 135 swings about the axis 137 carried by the bracket 12 ″ of the lever 12 and the paddle 134 lifts the bolt 144 which, under tension of the spring 143, brings the sleeve 151 into contact with the discharge terminal 147 . The electrical circuit of the relay, through which the automatic shutdown is effected, is closed, so that the entire device, namely the separating device, the sorting device and the separating or ejecting device, which are driven by a special motor.

f. Feed device for the middle aisle feeding the press-on machine

The feed device G for the middle gear / i feeding the press-on machine

(see Fig. 2i, 22, 23, 24, 25 and 26) consists essentially of two levers 153, i54> which swing around the axes 155 and 156 ', which are arranged on a plate 20 firmly connected to the frame and are connected by a strut 161 hinged to said levers with the aid of axles 162 and 163 in such a way that they form an articulated parallelogram. The arm 153 terminates at the opposite end opposite the hinge 155 in an operating handle 160; this arm and the end of the arm 154 move in two windows 157 and 158 which are provided in a projection 15g of the plate 20 and have the purpose of limiting the movement of the articulated parallelogram. The strut 161 receives the end of each of the esophagus E, E ' (see Fig. 25), which end flush with the underside of the said strut 161. Below the underside of said strut, for example, by screws 165 with countersunk heads, a plate 164 made of resistant metal, for example steel, is attached, which is provided with two bores 166, 167, the cross-sections of which, taking into account the grooves e, e ', correspond to the inner cross-sections of the Tubes E ₁ E ' correspond exactly.

The plate 20 (Fig. 21) carries a housing 168 which is provided with two windows 169, 170 which are narrowed in the lower part (see Fig. 24); on the rear part of the housing 168 are around an axis 173 two resilient levers 171, 172 articulated, which for example consist of two leaf springs, and which are pressed by their spring force against the right edges of the window 169, 170. These levers are each provided with a pin 171 ', 172', the width of which is smaller than the width of the grooves e, e '. Depending on whether the lever occupies the upper or the lower position in the corresponding window, the pin is located opposite the corresponding groove of the feed tube or penetrates into this groove 23 and 24, the lever 172 is in such a position that its pin 172 ' penetrates into the groove e of the pipe E and keeps the row of links immovable in this pipe t; the central pipe H is therefore fed by the pipe E ' which is directly connected to the central pipe. In order to feed the middle pipe with connecting links coming from the pipe E, the row of connecting links moving in the pipe E ^r should first be brought to a standstill; for this purpose it is sufficient to lift the lever 171 in the window 169. Because of its spring force, this lever lies against the right edge of this window, while the pin 171 'engages in the groove e' and locks the row of connecting links in the pipe E '. It is then sufficient to bring the joint parallelogram into the position shown in Fig. 25 by pulling on the lever 160 so that gear E is at the level of middle gear H. The width of the windows 157, 158 provided in the projection 159 of the plate 20 is dimensioned so that the two outermost stop positions correspond to an exact superposition of the one pipe E or E ' with the central passage H. Since the lever 172 has at this moment been brought into the lower part of the window 170, its pin 172 'emerges from the groove e , as a result of which the row of connecting links which has hitherto been brought to a standstill in this tube is released. The feed pipe E ' can be brought into coincidence with the central pipe H by a reverse operation.

The plate 164 made of resistant metal serves to prevent deformation of the ends of the tubes E, E ' in the event of incorrect handling. It could happen that the operator goes from one position of the operating lever: 160 to the other without stopping the movement of the connecting links. T. reaches into the middle aisle, then the force exerted on the end of the corresponding feed pipe would have the consequence that this, which consists of less resistant building material, is bent and thus unusable. " without further ado, and the operator, who is made aware of his mistake by the resulting resistance, can easily correct it.

G. Medium course

The middle feed course H (see Figs. 21, 22, 27, 28 and 29) consists essentially of a body which has an angle part 174 on one side, on which a block 177 is fastened by screws 178, which is fastened by pressure screws 181 is penetrated, which press a locking longitudinal plate 176 against bearing surfaces 180 which are provided in the body of the middle aisle. The pressure screws are held in their position by locking screws 179. On its side facing away from the closure plate 176, the middle passage H has a groove 17s which ends at the bottom in a window 175 ',

XO

which completely permeates the corresponding page. The closure plate is also pierced and has a window 176 'at the bottom and at the same height. ■. . The cross-section of the passage formed in this way corresponds to the passage cross-section of the feed pipes B, E ' .

The middle aisle Ii is connected to the machine frame 183 by two joint axes ™ 182, 182 ', which are arranged coaxially (Fig. 29). The upper part of the aisle H forms a bush 185 into which a fixed aisle i86 penetrates . is firmly connected by its support surface 187 to the plate 20 and whose cross-section also corresponds to the passage cross-section of the feed pipes B, B ' . The joint planes 184 having opposing only a very small amount of play, are in immediate ^z ° indirect vicinity of the horizontal plane containing the geometric center line of the joint 182, 182 'includes, whereby between the stationary and the movable part of the central passage, each interrupting ^a ver 5 is avoided, by which could fall out a link during a random vibration of the _t transition therefrom.

At the bottom the side surfaces of the middle aisle have two parallel "slopes 188, 189, which have the purpose of centering the guide groove 175 'so that the line of symmetry the links are in a vertical position when exiting the middle aisle.

The random oscillation of the middle gear, the causes of which will be given below, is inhibited by a spring 199 firmly connected to the frame, by means of which the gear H is brought back into the desired position. This position is determined by an adjustable stop 200.

H. The cutting hammer

* 5 The cutting hammer m (Fig. 2.1) is carried by an angle lever 190, which swings around an axis 191, which is itself carried by an angle piece 192 firmly connected to the machine frame. This angle piece 193 has a tail 193, antwelehem one end of a spring 196 is attached. The other end of this pen is. attached to a point 195 of the angle lever 190. The latter has a tendon 194, which is in contact with an inclined plane 197, which acts as a lifting surface and is driven by the main shaft JV. This lifting surface 197 lifts with each revolution of the. Wave N the hammer m, which is under the influence of the spring 196 and strikes against the lower part of the middle passage, whereby the links that are located in this passage H and are about to get caught are brought to fall.

The oscillation of the angle lever 190 is caused by the * stop of the projection 198 limits this angle lever against the angle piece 192.

2. The pressing machine a. Guide passage for the flexible strip Guide passage I for the flexible strip Strip (Figs. 21 and 35) is for receiving the flexible strip 23 through its part 249 determined, the one intended to receive the connecting links to be pressed open Bead forms. The only purpose of this tube I is to keep the tissue at the void height for pressing on.

80 b. The dispenser

The dispensing device O (Fig. 21, 22, 30, 31, 32, 33, 34, 36, 37 and 38) consists of a piece 201, which is designed as an open bracket in its lower part. At one end, this bracket has two right-angled bends 202, 202 'designed as a stop. At the other end, one flange of the bracket merges into a spur 203, the lower side 217 of which is designed as an inclined plane '(Fig. 30, 31), while the other flange is at a lower height than the spur 203 by a double right-angled bend 205 continues, which ends in a spur 204. As shown in Figs. 30 and 32, these two spores 203 and 204 lie one above the other and a space 206 is left between them.

A lever 207 slides inside the bracket 201, its rear slightly curved tail has an eye 208, while the front Tedl is provided with a vertical incision 209 is. In this incision is the rounded tail 210 of a thrust lever 211 stored, the one carried by the bracket 201 Axis 212 swings. This lever ends in one at its other end Beak 213, which in the position tiii shown in Fig. 30 grips an incision 214, which is provided in the foot of the spur 203, and its lower part 216 in the extension the lower inclined plane 217 of the spur 203 is arranged. A feather 218, on the one hand on a projection 219 of the bracket 201 and on the other hand at 220 on the sliding lever 207 is attached, usually seeks the sliding lever in the position shown in Fig. 30 bring to.

The bracket 201 is guided through a guide sleeve 221, the width of which by the Screws 222 (Fig. 21) can be adjusted. One with the two front panels

location surfaces of the sleeve 221 firmly connected Axis 223 passes through bracket 201 through two windows 224, 224 'and engages through Window 225 of lever 207; through this axis the whole thing is at the desired height held. In the rear part of the sleeve 221, the bracket with the associated Slide lever carried by a shaft 226.

The lever 207 is articulated at its rear end on an axis 227, which from Bracket 228 of a lever 229 (Fig. 33) is carried which has a stop 230 and above has a groove 231. This lever 229 is pivotably mounted about an axis 232 which penetrates its bracket and fixed with a part 233 carried by a holder 234 connected is. This holder is in a suitable recess by a screw 235 attached to the frame.

The axle 232 also carries an oscillating lever 236 which has a stop 237 and a groove 238 in its upper part. The oscillating lever 236 also forms a bracket 239 which ^{is pushed onto the end of the part 2} 33 and swings in the bracket 228 of the lever 229. The two upper ends of the levers 229 and 236 swing like tongs about the axis 232, and the closing movement is limited by the contact between the two stops 230 and 237. A spring 240, which engages with both ends in the grooves 231 and 238, seeks to bring the two oscillating levers into the position in which the stops are in contact.

The lower part of the bracket 239 is provided with two right-angled bends 241, 241 ' and carries an axis 242 which passes through a part 243 which is displaceable in the holder 234 mounted and guided through an axis 245 passing through the associated window 244 is. Each bend 241, 241 'is marked with the corresponding end of the axle 245 connected by a coil spring 246, 246 ', the usually the entire swinging lever in the tilted position shown in Fig. 36 holds.

The end of the part 243 slides in the associated holder 234 as a result of its contact with the lifting disc 247 which is seated on the main shaft N which is driven by the rope pulley 248.

The purpose of the dispenser 0 is:

i. those contained in the middle gangif To keep links therein;

2. to let them emerge one at a time;

3. to press it onto the tissue at the end of the stroke;

4. to hold it on the flexible strip during the pressing process.

In the rest position, the dispensing device O assumes the position shown in FIG. 30 and is held in this position by the spring 218 and the springs 240 and 246. In this position, the lower spur 204 engages in the windows 175 'and Γ76' of the middle aisle H, and above it sits the lowest connecting link Z _{1 of} the row of connecting links contained in the middle aisle at this moment. The upper spur 203 lies completely outside the middle aisle. As soon as the lifting disc 247 acts on the end of the part 243, this part is advanced, its movement being transmitted to the tail of the lever 207 through the intermediary of the entire oscillating levers 229, 236. This lever, which is connected to the bracket 201 by the spring 218, moves the whole thing to the left. The spur 204 therefore moves away to the left of the aisle H, while the spur 203 approaches it and penetrates its windows 175 ', 176'. It thus engages between the legs of the connecting link Z ₂ located directly above the connecting link Z and holds it in place.

It should be noted that all the connecting links are in the correct position after they have passed through the sorting device, that is to say they are all with their legs pointing downwards. The spur 203 can therefore freely engage between the legs of the connecting link Z _2. However, if, which is very unlikely, a link is upside down or does not fall completely, the end of the spur 203 would hit the projection of this link, which would damage the feed duct and the dispensing device at the same time. This is avoided by the oscillating arrangement of the middle feed aisle. In the present case, the corridor would then swing a little about its axis so that the dispensing device can continue its movement without damage. This device itself would then not suffer any shock which could damage it, because the two stops 230 and 237 would move away from each other in a tong-like manner as a result of the resistance encountered by the end of the device, the spring 240Men shock being dampened. A double safety device is therefore provided, which is formed at the same time by the oscillating arrangement of the feed path and by the play of the resilient connecting member which transmits the switching movement to the device.

The movement of the bracket 201 now continues and the spur 204 leaves the

binding link Z ₁ , which was held in place by said bracket. This link usually falls under the influence of gravity. Its fall is accelerated by the contact of the upper part of the connecting link with the inclined plane 217 of the spur 203, which continues through the lower part 216 of the thrust lever 211. The connecting link Z ₁ is therefore guided until it straddles the bead 249 of the flexible strip 23.

At this moment the bends meet 2O2> 202 'of the bracket 201 against the rear wall of the guide sleeve 221, whereby the movement of the bracket and the spurs 203 and 204 is limited. The Evil 207 continues on its way and swings the push lever 211 about its axis 212; the

ao beak 213 presses firmly on the upper part of the connecting link Z ₁ during its downward movement, which is thus firmly pressed onto the bead 249 of the flexible strip 23.

The cam disk 247 gradually gives the lever 207 as it continues to rotate free. During the first part of this movement, the one held by the spring 218 in FIG

. its position held bracket 201 of the fermentation device immovable; as a result, the beak 213 of the lever 211 is brought back into its recess 214 provided in the foot of the spur 203. Then the entire dispensing device executes a backward movement, and the spur 203 slides under the connecting link Z ₂ , which it supports up to the Atigenblick, where it leaves this link, which then straddles under the influence of gravity and the blows of the cutting hammer m the spur 204 falls.

The whole thing has now returned to its original position, and the same process begins all over again.

c. The tissue forceps

The, tissue forceps / (Fig, 21, 22, 39, 40) consists of two symmetrical legs 262, 262 ', which are rotatably mounted about axes 250, 250'. The latter are firmly connected to a holder plate 251 (Fig. 21, 40) fastened to the frame 255 by means of screws 270. The two rear ends of each of the legs 262, 262 'are moved against one another by a spring 386 when the tongs are open. The two front ends of the legs 262, 262 'each have a longitudinal groove 271, 271' (Figs. 22, 39); when the two legs are brought closer to each other, the grooves form a recess into which the bead of the flexible strip is inserted. In addition, these ends have angular recesses 302, 302 ', the depth of which corresponds to the thickness of the projection 2 of the connecting links Z. A lifting disc 252 ″ seated on an axle 253 causes the. Closing of the pliers / through its projections. The axle 253 is rotatably mounted in a suitable holder in the frame 255 and is continued by a square 254, to which thread 256 is connected provided with a square hole 258 arm 259 is pushed onto the \ ^r ierkant 254 and is held by a nut 257 in the vertical position. the end of the arm 259 is connected through the intermediary of an axle 261 to a bracket 260 which itself with a rod 263 is fixedly connected, which carries a bracket 264 at the other end; the latter carries an axis 265 on which the end of an angle lever 266 is articulated, which swings about a fixed axis 267, and the other end carries a pin or a roller 268 which cooperates with a cam disk 269 seated on the main shaft N.

Through the cam disk 269, the lifting disk 252 is mediated by the above described linkage communicated a swinging movement, which the closing the jaws of the tissue forceps causes their opening movement then under the influence the spring 386 takes place as soon as the lifting disc 252 has left the legs 262, 262 '.

The tissue forceps closes before the delivery device begins to move and remains closed for the entire duration of the pressing process.

d. The press-on pliers

The Aufpreßzange K (Fig. 21, 22, 39) consists of two symmetrical legs 272, 272 ', which are articulated about axes 273 and 273', which are themselves firmly connected to a projection 300 of the frame and in the open position under the Influence of a return spring 274 stand. The front part of each of these legs has a removable rivet punch 275, - 275 '; These riveting dies each have a recess 301, 301 ', the depth of which corresponds to the thickness of the connecting links Z. The rear ends of the legs 272, 272 'have adjustable bearing surfaces which are formed by wedges 276, 276' which are firmly connected with screws 277, 2, Jj ', with adjusting wedges 278, 278' and countersunk screws 279, 279 '. A lifting disc 280, which is loosely seated on the shaft N and provided with two sets of lifting cams, is driven by a drive wheel 282 which meshes with a drive wheel 283 which is keyed on a shaft 284 which carries a drive wheel 285 at the other end, which with

a driving wheel 286 seated on the main shaft N meshes. This gear transmission has a transmission ratio with a transmission to slow speed, which is selected so that the lifting disc executes a full revolution for every two revolutions of the main shaft N , which is the arrangement of the two lifting cam sets 287, 287 'and 288, 288' on the lifting disc explained.

When the parts a, b, a /, V of the lifting disc 280 lie against the bearing surfaces of the legs 272, 272 'of the press-on pliers K , the sacks 275, 275' are farthest apart. The tissue forceps / is open for the corresponding duration of the stroke disk rotation. At this moment the projections 287, 287 'come into contact with the bearing surfaces of the legs of the crimping pliers, whereby the jaws of the latter are brought closer to one another, and the recesses 301, 301' of said jaws with the corresponding recesses 302 and 302 'of the jaws the tissue forceps, which has just closed, form a guide passage, the cross-section of which corresponds to the cross-section of the middle feed passage. At that moment the dispenser will move forward until the spur 204 releases the link it is carrying. The latter is guided by its projection in the passage formed by the two recesses 302, 302 '; the link then falls astride the bead of the flexible strip. The beak 213 of the oscillating lever 211 then presses on the tip of the connecting link, which is thereby pressed firmly onto the bead of the flexible strip, whereupon the lifting disc brings its projections 288, 288 'in front of the contact surfaces of the pliers, whereby the jaws 275, 275 'are approached and the connecting link is pressed onto the strip. While the dispensing device is now returning to the initial position, the lifting disc has continued its rotation and parts a, b, a ', V have adjusted their circumference, which corresponds to the largest opening of the legs of the press-on pliers. Meanwhile, the tissue forceps has let go of the flexible strip which, under the influence of the associated drive device, moves forward by the distance between two successive connecting links. The process then starts all over again.

e. The drive device for the fastener tape

The drive device L (Fig. 21, 22, 41, 44) consists of a carriage that moves back and forth.

This reciprocating carriage has a side member 289 that supports the stationary Legs of the tongs that convey the tape, and at both ends in shields 290, 290 'is inserted. These shields carry by means of screws 291, 291 ' Raceways 292, 292 ', which run on rollers 293, 293', which are in the with the frame 295 firmly connected boxes 294, 294 'held are. The carriage is supplemented by a movable clamping leg 304, the pivot axis of which 303 is rotatably mounted in shields 290, 290 'at each end; by one in the recesses 306 and 307 of the stationary and movable legs of the pliers arranged spring 305, the latter is kept open. The longitudinal beam 289 carries a projection 308 which itself has an axis 309 which is held in place by a screw 309 '; on axis 309 a lifting disk 310 firmly connected to the handle 311 swings.

The carriage of the conveyor belt feeder is driven by a drive wheel 297 which meshes with the rack 296 of the carriage. The drive wheel 297 is keyed on an axle 25, which is in the frame 298 of the escapement block is rotatably mounted and the ratchet wheel 312 with the freewheel device 313 carries the drive of the movable carriage in only one direction enables.

On the other hand, there is a spring housing 24 connected to the carriage by a band 387 constantly striving to move the carriage to the right in Fig. 21.

The frame 298 also carries, through two counterpeaks 314, 314 '(Fig. 41), the kimkenblock3i5, which is pivotably mounted on these counterpeaks an angled tab 317 (Figs. 41, 44) with an angled right bend 318 which forms a tail on which a rod 319 is attached. The latter is connected by a rod 320 to one end of an angle lever 321 which carries a sleeve 322 which is pushed onto an axis 323 carried by the frame. The same end of the oscillating lever 321 is connected to a fixed point 326 of the frame by a spring 325, which endeavors to bring the other end of the angle lever with a lifting disk 324 seated on the main shaft N into contact.

The escapement block 315 has a fixed pawl 327, and behind this is a movable one Pawl 3 28 arranged, which swings about an axis 329 and as a result of a spring 330 strives, with a stop 388 in

To kick in touch; a support surface 33.1 provided in the escapement block serves as a Stop for the lower surface of the movable pawl 328, the top of which is in this Position in the same plane as the fixed one Pawl 327 is located. By, one on the one hand with the Hemimmgsblock3i5 and on the other hand Spring 332 connected to the holder frame, the block is constantly with the driving force lobes 317 held in contact.

The operation of the drive device described above is as follows.

As long as the end of the bell crank 321 remains in contact with the circular part of the lifting disc '5 324, the various. Connecting parts have such a game that the fixed pawl 327 is under one of the teeth of the ratchet wheel 312, which is thereby held; which is under the influence of the _; Spring housing 24 stationary movable carriage can not move. But as soon as the end of the angle lever 321 'reaches the slope of the lifting disc 324, its other end pushes the rod 32O to the left; the latter, through the intermediary of the rod 319, exerts a pull on the tail 318 of the part 316, the lobe 317 of which swings forward. The pawl block 315 held in contact with the associated movement tab 317 therefore rotates in the same direction, and the tooth of the ratchet wheel is released from the fixed pawl 327. The carriage driven by the spring housing moves to the right in Fig. 21 and, through the toothed rack 296, takes the toothed wheel 297 and the ratchet wheel 312 with, which is firmly connected to said toothed wheel; this ratchet wheel therefore rotates in the direction of the arrow (Fig. 41), and the next tooth hits the end of the movable pawl 328 and takes it with it until it hits the fixed stop 331 and is thereby stopped the carriage ♦ 5 to a standstill, which has been displaced by an amount which corresponds to one tooth width of the rack, ie the distance between two successive connecting links on the flexible strip. When the tab 317 returns to its initial position, it entrains the arresting block 315, which swings around the tips 314, 314 '. This causes the movable pawl 328 to snap out, which under the influence of the associated spring 330 into the one shown in Fig. 41 apparent position returns, while the tooth previously held by the movable pawl comes into contact with the fixed pawl appen to be shifted again by an amount that corresponds to one tooth width of the rack. It should be noted that the snapping takes place immediately after the largest opening of the press-on forceps and the tissue forceps, while the dispensing device is at a standstill. The consequence of this is that the movable carriage, the tongs of which constantly compress the flexible strip intended to receive the connecting links, is displaced at the moment of snapping out by an amount which corresponds to the distance between two successive connecting links. The attachment of the next connecting link can therefore take place in the manner described above.

f. Automatic device for interrupting the pressing of closure members, and Regulating the length of the section of tape that "should not receive any fastener links."

■ The automatic device M for interrupting the pressing and for regulating the length of the band section which should not receive any closure members (Fig. 21, 22, 42, 43 and 45) has a fixed stop 299, which determines the beginning of the pressing; a locking cam 26 is movably arranged on a toothed rack 27 which has pitches and by means of which the number of connecting members to be pressed onto the flexible strip is set according to the length required for the desired closures. The cam 26 is pushed against the stop 299 at the beginning of the work with the rack.

When the desired length has been reached, the automatic stop is activated causes a thumb 29, which is firmly connected to the movable carriage and hits against a part 28 which is under the influence of a spring 334 and about an axis 333 swings. This part 28 ends at the bottom in two legs, one of which is one Locking hook 335 has, while the other, 336, on a shaft 337 has a swinging Locking part 338 with a locking hook 338 'carries the tail 339 by a spring is connected to the end of the leg 336.

A lever 30, which is provided with a stop 342 in a slot 341 Holder is slidably mounted, carries at its end a sleeve 343 on a Axis 344 is keyed, which between white counterpeaks carried by the frame and 346 swings. On this axle 344 (Fig. 42) a link 347 is keyed, the via a rod 348 with a lever 349

is connected, which carries a plate 352 at its right-angle bend 350, which swings about an axis 351 fixedly connected to the frame.

This oscillating plate 352 is recessed at 352, '(Fig. 45) to allow the passage of the shaft AT - and, through axles 356, 357, carries levers 354, 355 which are connected to one another by a strut 358 in such a way that that a deformable parallelogram is formed, the displacement of which is made possible by the sliding of the ends of the levers 354, 355 in the windows 359, 360 provided in the projection of the plate 352. »5 The plate 352 also has two windows 362, 363. The lever 354 bears on the bottom of a fixed locking cam 364 which protrudes from the window 362 and the lever 355 bears in a similar manner a ^{2 (>} fixed locking cam 365, the group consisting of the window 363 extends. the lever 354 also carries by a shaft 366, a flat spring 367, a movable cam is mounted 368 on the underside thereof, by a FEN ^Z 5 most of the same dimensions protrudes, which is provided in the lever 354, and further engages and protrudes from the window 362 of the plate 352. This movable locking cam has an inclined plane which is not visible in the drawing.

The swinging lever 354 has near its end a bracket 369, the one Axle 370 carries around which a handle 371 swings, which merges into a tail 372, which under the influence of one between the handle and the end of the swinging lever 354 engaged spring 374 in one of the two notches 373, 373 ', which is provided in the upper wall of the projection 361 of the plate 352 are.

The swinging lever 355, like the swinging lever 354, carries a movable one Cam 375 with an inclined plane 375 '(Fig. 42); this cam is at the end a flat spring 376 attached to lever 355 at 377.

Wedged on shaft N is a part 378 (Fig. 43) with a stop 382 'and a tail 379 which is connected to a vibrating part 382 by a spring 380. The latter is provided with a stop 385 and firmly connected to an axle 381 which is rotatably mounted in part 378 and on which a pawl 383 is wedged. The latter is usually under the influence of the spring 380, which tends to bring the pawl 383 into engagement with a ratchet wheel 384 which is firmly connected to the drive wheel 248 which is loosely seated on the main shaft N.

The main shaft N is therefore driven by means of the ratchet device, which consists of the ratchet 384 firmly connected to the drive wheel 248 and the pawl 383 under the influence of the spring 380. As already mentioned above, the start of pressing is determined by the contact between the adjustable stop 26 and the fixed stop 299. When the machine is set in motion by the main shaft N , which itself receives its drive from the ratchet device described above, the connecting links are automatically pressed onto the flexible strip by the pressing machine at the desired distance from one another. When the number of connecting links to be pressed onto the flexible strip in this way has been reached, which number is determined by the position of the adjustable stop 26, the thumb 29 hits against the oscillating part 28, which thereby pivots to the right (Fig. 21) will; As a result, the jaw 355 releases the lever 30, which slides under its own weight in its guide 341 and strikes the associated stop 342, while the oscillating part 338 swings out under the influence of the associated spring 340 and adjusts its jaw 338 'with respect to the guide 341 , whereby any lifting of the drive lever 30 is prevented as long as the oscillating part 28 has not yet been released, that is, the rack 27 is not pushed back.

When it falls, the lever 30 swings about the tips 345, 346 and takes the handlebar 347 (Figs. 21 and 42) with it, which is lifted and takes the rod 348 with it and, through the intermediary of the rod 349, the swinging plate 352 down around the axis 351 pivots. This plate then brings its fixed locking cam 364 carried by lever 354 into the path of stop 385 of part 382; the latter then swings out to the left and takes the pawl 383 with it, which releases the ratchet wheel 384. The latter then rotates loosely on the shaft N with the wheel 248. The shaft initially continues until the stop 382 'hits the inclined plane of the movable cam 368, which yields and returns to its position through its retaining spring 367 and the part 382 'holds on. The main shaft N is thus disengaged and the machine is at a standstill, the tissue tongs and the press-on tongs then being completely open. It is then sufficient for the operator, after he has released the movable jaw 304 by operating the handle 311 of the lifting piece 310, to move the flexible strip forward a length.

pushes, which corresponds to the distance between two consecutive locking parts, which are formed by two rows of pressed-on connecting links, and the Carriage then move back, which is done by the free-wheeling device of the jamming device is made possible, and this movement lasts until the adjustable stop 26 comes into contact with the fixed stop 299. Then the movable one is Bring jaw 304 back into pressure position on the flexible strip. if the operating lever 30 is lifted, so it engages under the hook 335 of the swinging Part 28 and lifts the oscillating plate 352, thereby releasing the pawl 383 which meshes with a tooth of the ratchet wheel 384 and the main shaft 2V again drives. The process then begins anew.

It should be noted that the length of the displacement of the carriage may be too short for the length of the desired closure member, which consists of a series of pressed-on links; in this case the adjustable stop 26 is brought into a position which corresponds to half the useful length of the desired closure part. Then the beak 372 of the handle 371 actuating the lever 354 is brought into the incision 373, whereby the joint parallelogram is deformed in such a way that the stops 375 and 365 of the lever 355 are brought into the path of the stops 382 'and 385. The pawl is disengaged in the manner described above with a shift of half a turn of the shaft N. This shift brings the machine to a standstill in the press-on position, i.e. the tissue tongs remain closed on the flexible strip and the press-on tongs remain on the one that is being pressed on located connecting link applied. The operator can therefore return the carriage to the initial position without jeopardizing the setting, in order to complete half of the closure part still to be produced, and start the machine again by actuating the lever 30. However, he must move the articulated parallelogram of the oscillating plate again in order to advance the tissue at the end of the second carriage stroke by the length by which two successive rows of connecting links are separated from one another. In this case, it is necessary to operate the operating lever 371 every time the car is lifted.

It goes without saying that closure parts of any length can be produced in this way can that one divides this length by a number of divisors, which the number of operations certainly.

The semi-automatic device described above offers advantages in certain cases, but has the disadvantage that it requires operator intervention to bring the car back to zero and for the Adjustment of the distance that is pressed on the fabric between two rows of Connecting links should remain free. Add to this if the length is desired Closure part is larger than the carriage displacement, the execution of several Handling on the vibrating plate.

This disadvantage is avoided by an automatic drive device which ensures uninterrupted and faster work.

G. Automatic device for the movement of the flexible strip, the interruption of the pressing, the adjustment of the length of the row of links, the "pulling of the tape after the setting" of a row of links _g and for the restart of the pressing

In this arrangement, the reciprocating carriage L is omitted * and is replaced by two drive wheels 31 and 32. The go wheel 32 sits on the jamming device 298, which was already mentioned in the semi-automatic device, and is connected to the shaft 25. The wheel 31 is carried by the lever 33 which is arranged to be movable about an axis 34 and is held in contact with the wheel 32 by the spring 35.

The support belt 23 is clamped between these two wheels, the contact points of which are located just below the press-on point, that is to say exactly below and in the middle of the two press-on jaws of the pliers K.

In front of the wheels 31 and 32 there is the switching drum 36. The fabric 23 is on this drum is pressed by a series of springs which carry rollers on one Brackets 37 are arranged, which is under the influence of a return spring 37 " provided lever 37 'is. The drum 36 rotates freely about its axis and is Provided with a ratchet wheel 38 at the bottom. A pawl 39 controlled by the lifting disc 40 which sits on shaft 284 (Fig. 21), and through intermediation two levers 41 and 42 wedged on the same axis 41 'act, moves this ratchet wheel after pressing on the individual connecting links.

The movement of the thumb 40 has caused the spring 42 'to be tensioned was, through the intermediation of levers 41 and 42, the pawl 39, the small from

Bracket τ ,? supported rollers and the drum 36 exerts a tension on the fabric strip 23. Since the tissue is firmly pressed between the wheels 31, 32, it can only move forward if the inhibition 298 (Fig. 48) allows this; As a result of this inhibition, the ratchet wheel 312 can only turn one tooth at a time (Figs. 21 and 22); this escapement works by the levers and mechanical means already described. The wheel 31 is lifted from the wheel 32 only after the automatic disengagement device has worked at the end of the pressing process, ie when the connecting links to be pressed on are present in sufficient numbers on the strip 23. By lifting this wheel 31, the tissue 23 is to be separated from the pressing device, so that the tissue 23 can be connected upstream by a certain amount without pressing on connecting links.

The drum 36 carries a gear 43 keyed on its underside with a Gear 44 meshes, on the axis of which a gear 45 is keyed; the latter combs with the gear wheel 46, which rotates loosely on the axle 61 (Fig. 47) on which the Drum 36 is also loosely rotatably seated.

Through the intermediary of the gears 43, 44 and 45, the gear wheel 46 is therefore four times slower than the drum 36th rotated. This device has the purpose of the first drum 48 of a number counter with a quarter to drive the speed.

The axle 55 (Figs. 46 and 49) is driven by the rack 56 which is driven by the Spring 56 'is pulled. This spring became with a previous rotation of the axis 61 through the intermediary of the connecting rod 402 of the lever 401 and the carriage 400 cocked. She can only relax when it's done by the electromagnet 53 and 73 controlled anchor escapement 54 allows (Fig. 46).

The gap 399 of the rack 56 serves the further rotation of the axis 61 and the associated crank 402 by driving the carriage 400 through the intermediary of the lever 401 to enable; As a result, the through the rack 56, the drive wheel 397, the Axis 55 and the anchor escapement 54 retained spring 56 'remain taut.

The rotation of the shaft 61 is brought about by the fact that the shaft 61 on said shaft wedged automatic stop 67 comes into engagement with the disc 68, which by the Motor of the press-on device is kept in constant rotation. The shaft 55 becomes controlled only by the spring 56 'which is self-adjusting with each rotation of the shaft 61, i. H. only is stretched when pulling through the fabric without pressing.

The anchor escapement 54 is intended to allow this shaft 55 to rotate only at the exact moment enable the electromagnets 53 and 73 to operate. The 397 wheel is just a free wheel and should first tension the spring 56 'without taking along the axis 55 and then allow the rotation of the shaft 55 by relaxing the spring 56 '.

The foot of the drive wheel 46 carries a claw 47 through which the first toothed drum 48 of a counter is driven.

The translations of these individual gears are chosen so that one revolution the drive drum 36 corresponds to the placement of forty closure members, wherein the drum 48 makes four revolutions.

The other counter wheels naturally act according to the principles for the successive one Drive all totalizers.

Each meter drum carries a ring 49 which is movably arranged around the drum and divided from zero to nine (Figs. 46, 47). The number zero corresponds to a lead 50, which can actuate an electrical contact 51 each.

All the contacts are connected in series so that the current only flows then can when all contacts are closed, d. H. when all counter rings are brought back to zero have been.

When producing a series of closure parts of the same length, the number, which represents the number of connecting links to be pressed on, must therefore be set or set once and for all with the aid of said rings 49 before the machine is started up. After the connecting links have been pressed on in sufficient number, all rings return to zero, the circuit of an electromagnet 390 being closed, which is shown in phantom in Fig. 21, and attracting the vibrating part 28, which around its axis 333 oscillates and in this way actuates the automatic release device M in the manner described above.

The pressing is interrupted at this moment.

The lever 30 (Fig. 51) of the automatic Release device carries an insulating part 391, which itself carries a contact sheet 392, that when the lever 30 falls, the circuit of two contacts 393 and 394 closes, which of an insulating plate 395 can be carried. Contact 393 is with the one, here connected to the positive pole of a suitable power source, while blade 394 is connected to is connected to contact 396 of a manifold 52 (Fig. 46), which loads a conductive portion 52 '

i8

sits and actuates the electromagnet 53, the controls the first stroke of the anchor escapement 54, which enables the rotation of the shaft 55. The bearers, at their end (Fig. 46, 49) the drive wheel 397 with freewheel device, which is connected to the rack 56 combs, the smooth ends of which slide in guides 398 and 398 '. This rack is below the influence of the return spring 56 ', which is connected at one end to the bearing 398, and laterally has the window 399 in which the movable carriage 400 slides, the ' is designed as a double T-piece (Fig. 50) and is operated by the handlebar 401, which is attached to the crank 402 keyed on the shaft 61.

A cam disk 57 wedged on the shaft 55 acts on the lever 33, which controls the Wheel 31 carries and removes the latter from the wheel 32; At this moment the fabric 23 is no longer held by the wheels 31 and 32.

At the beginning of the rotation of the shaft 55 and at the same time as a lifting disc 58 acts on the lever 59 in such a way that the whole Counter can be decreased by a certain amount. This lowering movement is controlled by a bracket 60 (Fig. 46, 47), which serves to keep the counter device in its position. keep. The claws47 have them Leave the claws of the gear 46. The shaft 61 which holds the entire counter and drum 36 carries is provided with a series of pins 62; on the other hand, the drum counters wear one pin 63 each; by the lowering movement of the counter, these pins 63 are brought into the path of the pins 62. At her further rotation controls the shaft 55 through the intermediary of a cam plate 64 and one Lever 65 pushing back a part 66, which in turn engages the automatic Disengagement device 67 for the shaft 61 with the disk 68 allows. The disc 68 is continuously due to the special motor of the entire press-on device Rotation held.

The automatic disengagement device 67 keyed on the shaft 61 is set so that it only makes one full revolution and stands still at a certain fixed point each time. As a result of the rotation of the shaft 61, the pins 62 have come into contact with the pins 63, as a result of which the wheels 49 are returned to their original position and thus reset the number corresponding to the number of connecting links to be pressed open. The shaft 61 simultaneously drives the drive drum 36 through the intermediary of the freewheeling device 69 and the sets of gears T ₁ T ' , whereby the fabric is advanced by the necessary length between two rows of pressed-on connecting links.

The first bar of the escapement is over. The second measure begins now. In its current position, the shaft 55 has the distributor 52 in contact with the brush 70 brought; under the bracket 60 • (Fig. 46, 47) the circuit is also closed by a hub-like ring 71. Through the intermediary of the contacts 72, the brush 70 and the distributor 52, the second cycle of the escapement 53 is through a solenoid 73 controlled; as a result, the shaft 55 ends its rotation. the Lifting disk 58 keyed on shaft 55 lifts bracket 60 through the intermediary of the Lever 59, whereby the claw 47 with the • claw of the drive wheel 46 again engages is brought. During its upward movement, the bracket 60 entrains the entire wheels of the meter and pulls the pins 63 back off the track of pins 62. The wheel 31 again presses the belt 23 against the wheel 32. In addition, the bracket 60 has influenced a contact 403 during its upward movement, which by mediation of the contact 404 and the time relay 406, which sits on the lever 30, the circuit of a diver go electromagnet 405 closes.

The contact 403 is with the one, namely here the positive pole of a suitable one Power source connected.

The electromagnet 405 then pulls the lever 30, which swings around its axis and takes the time relay with it, which then responds. This relay, which can for example be of the type customary in light advertising systems, is set for a period of three seconds; after this time has elapsed, the current through the electromagnet 405 stops. Meanwhile, the lever 30 has come into engagement with the stop and now acts through the associated linkage described above on the automatic disengaging device M to restart the press-on machine, whereupon the same work process begins again.
