METHOD OF AND MACHINE FOR THE PRODUCTION OF SHEETS OF FLAT MATCHES I Filed Feb. 15. 1932 6 Sheets-Sheet 6 Patented June 19, 1934 PATENT OFFICE METHOD OF AND MACHINE FOR THE PRO- DUCTION OF SHEETS OF FLAT. MATCHES Jacob Briigger, Frut'igenpswitzerlan'd Application February 15, 1932, Serial No. 593,157 In Switzerland February 20, 1981 18 Claims. (Cl. Pi l-50) This invention relates to the production of sheets of flat matches and splints of which are connected to each other at one end.

' In the known manufacture of sheets or cards of this kind, the cards which have been out from wet wood are first trimmed and the matches are formed by stamping out their tips and severing them at their flanks to the required size, then the cards are successively subjected to the stamping, impregnating and drying operations. With this sequence of working incidences, particularly, the outer matches of a card usually became unequal, as the wood remained moist until after the stamping operation, thus having time for warping.

The object of this invention is to avoid these disadvantages by taking the web of material obtained in a match-stock-cutting machine and feeding the same forward in the longitudinal direction and successively impregnating, drying and stamping the sheets of matches therefrom.

This method permits of subjecting the material to the stamping operation in a dry condition, so that subsequent warping of the wood is rendered impossible and a series of sheets or cards for producing matches therefrom of uniform width throughout is obtained.

The machine for producing cards of fiat matches, the splints of which are connected to each other at one end, by means of the method according to the invention is provided with an impregnating device for the material for the matches and a drying device correlated thereto which is succeeded by a stamping device, the arrangement being such, that the material for the matches passes through the impregnating device first and through the stamping device last.

The method according to the invention is hereinafter described by way of example only and by taking reference to the drawings in which a constructional form of a machine for carrying out the method is illustrated.

Fig. 20 depicts a longitudinal elevation of a second constructional form of the stacking device,

Fig. 21 is a top plan view of Fig. 20, and

Fig. 22 illustrates a view of a detail on a larger scale.

Referring particularly to the Figs. 1 and 2 of the drawings, at the one end of the machine a winding device V for a web of material for the matches, for example of wood, is arranged, which is provided with a plurality, for instance twelve, individually rotatable supply rolls each to carry a web B of fresh, i. e. wet wood.

From the winding device the webs B pass over guide rolls through an impregnating tank 'J in which the webs are impregnated to the desired degree and eventually dyed a suitable color.- After the impregnation the webs B travel on a conveyor band 6 through a drying chamber K, whereupon they enter in completely dry condition in a stamping device arranged infront of the drying chamber. During the passage through the drying chamber the webs are subjected to a uniform longitudinal tensioning by means of a stretching device. This stretching device is composed of the pairs of rollers 1, 2 and 30, 31 respectively which are arranged at the entrance for the webs B in the drying chamber K as well as at the exit for the same. The first-mentioned'pair of feed rolls is driven from the conveyor band 6 in continuous manner and the latter in intermittent manner from the drive W of the stamping device. There is sufficient elasticity in the web of material itself to permit the resulting stretching effect. After leaving the stamping device the definitely stamped and severed match cards are received by a transfer device P in which a transmission drum 69 for conveying the match cards to trays R for stacking the same is provided, from which trays the match cards are subsequently taken off to be subjected to the further working stages.

With the aid of the hereinbefore described machine the method according to the invention is altogether automatically performable until the stock material on the winding device V is exhausted.

In the Figs. 3 to 7 the machine frame M constitutes for the main part a drying chamber and carries at its rear end the impregnating device J and at its front end the stamping device S. The supply rolls V for the webs of material to be worked are arranged below the impregnating device in the example illustrated in the number of twelve, and the arrangement is such that each two adjacent rolls are staggered in the longitudinal direction of the machine in order to provide the necessary space for their bearings. From the supply rolls the webs B pass to the impregnating device and from thence to the feed roll 1, a removably mounted counter roll 2 being provided for pressing the webs against this roll. The feed roll extends in one length the full width of the machine, whereas the counter roll is subdivided correspondingly to the number of webs. For mounting the counter roll, bell crank levers 3 are arranged on the machine frame the respective upwardly directed arm 4 of which is engaged by connecting rods 1'7.

To the side plates of the machine, on the inside of the drying chamber, rails 5 of angular crosssection are connected on which link chains 6 are running, the respective links of which being interconnected by transverse trusses '7, thus forming a continuous conveyor band for carrying the webs B of material. For guiding these webs laterally, the trusses 7 are provided at regular intervals with small stirrups 9 which are spaced only the distance of a wooden web apart. The chains of the conveyor band are passed over end rollers 10, 11, the forward roller 10 being actuated by themain drive of the machine by the intermediary of a speed translation gear whereas from the shaft of the rear roller 11 of the feed roll 1 for the wooden webs is driven by means of a spur gear drive. The lower portion of the conveyor band is also guided on rails 5a of angular cross-section.

Oh the shields of the machine bearing supports 12 are. provided in which shafts 14 are mounted. On the outside of these supports on the shafts 1.4 levers are arranged, namely at the forward pairofsupports bell crank levers 15, 16 and at the rearward pair one armed levers 15, the downwardly directed armsl5, 15' at the two supports on one side of the machine being interconnected by the rod 17. This rod extends in the, path of the respective lever arm 4 as abovesaid by means of which the lever arms 3 carrying the counter rolls are rocked. The forwardly and obliquely upwardly extending arms 16 of the bell crank levers are engaged by a rod 18 which on its other end is linked to the free end of the one arm of a bell crank lever 19, the other end of which carries a roller engaging a cam disc Kb. On the inner side of the bearing supports the shafts of each pair of these supports carry fixed laterally forwardly projecting arms 20 and between the two arms of each pair of bearing supports a supporting beam 21 of a square crossesection (Figs. 5 and '7) is arranged and on each beam twelve rod-shaped hangers 22 adjustably secured which are. suspended exactly above the middle of the wooden webs B. To each pair of longitudinally lined up hangers a press-bar 23 is pivotally connected the rear end of which is bent upwardly in the manner of sledge-runners and which in the inoperative position rests against the wooden web B underneath so as to load the web for straightening or dressing purposes. In the forward bearing supports of the machine frame an axle 24 is mounted to which inner lever arms 25 are secured. The two levers of the pair of bearing supports are inter-connected by a rod 26 which bears on a nose 27 on each press-bar 23. Exteriorly on the axle 24: an arm 23 is provided to which a rod 29 is connected, the other end of which is linked to a bell crank lever actuated by means of the cam disc Ka. When the rods 18 and 29 are moved by action of the related cam discs in the direction of the arrow, the arms 20 are swung upwardly, thus slightly raising the press-bars 23, whereupon the rocking motion of the arm 28 effects a rearward motion of the press-bars and thereby a further lifting of the same in the position shown in chain dotted lines in Fig. 7, the supporting beams 21 being correspondingly rocked about their journal pins. 7

Ahead of the conveyor band the stamping device St is situated to which the wooden webs are fed directly from the forward roll 10 by means of the pair of feed rolls 30, 31.

The operation of the described device is as follows:

The feed rolls 1, 2 impart to the webs of material B acontinuousadvancing movement on the conveyor band, where they are loaded by the press-bars 23, towards the feed rolls 30, 31 which in turn convey the wooden webs intermittently to the stamping tool, whereby each time during the short period between stamping incidences the stamping tools 39, 41 stamp out a series of matches from each web. Each time the rolls 30, 31 impart an intermittent movement to the webs. a stretching of the webs results which is again equalized by the continuous rolling of rolls 1, 2. As soon as a number of matches corresponding to the width of a card is stamped out and cut off the press-bars 23 are retracted-from the webs together with the counter feed roll 3 in the above-described manner, thus permitting the webs to equalize in length unhindered, since also the continuous advance movement is then stopped. Thereupon the retracted bars are again lowered and the stamping operation resumed.

7 Owing to the described arrangement the wooden webs are laterally guided in exact manner and permitted to expand and shrink freely in periodical time intervals, so that the occurrence of occasional internal tensile stresses or warpings is prevented from causing irregularities in the stamping eiiect or even rupture.

For a thorough understanding of the stamping device illustrated in the Figs. 8 to 16, Fig. 15 will serve to illustrate a match card stamped out from a wooden web including ten matches of the width b which represents at the same time the feed step of the intermittently advanced web. This figure shows plainly the slits t between the matches and the apertures Z between the tips of the same which are producedby stamping out correspondingly shaped tongues of material. The definitely stamped card is cut off during the last stamping stroke along the line T by means of a separate cutting blade while the advancing movement is interrupted. Alternatively, as shown in Fig. 16, in a wider web of material the tips of the matches may be stamped out at both longitudinal edges and. then the web folded about a scored line L spaced from its centre line so that the match tips come to lie in offset relation, as shown in dotted lines on the right hand side in this figure.

The stamping device is provided with two side shields 32 attached to the frame of the matchmaking-machine not shown in these figures, and formed at their upper part with a vertical slot 32a for guiding the cross-piece 33 for holding the stamping tools. In the latter a number of tool holders 34a, equal to the number of the webs of material, in the present case twelve, are vertically displaceably inserted, a set screw 35 screwed in the cross-piece for the tools from above serving as a stop member for each tool holder and a head screw 36a screwed in from the side as a fastening means. For moving the cross-piece 33 for the tools up and down connecting rods 37 are provided which act on pins on the cross-piece that project laterally through the side shields 32 and which are actuated by eccentrics 38 carried by the main drive shaft W. To the lower end ofv each tool holder 34a a flat stamping blade 39 extending transversely of the web of material is screwed, the blade being provided with longitudinal slots for engaging connecting screws 39a, so as to permit of adjusting the blade to the requisite height. The width of the stamping blade corresponds to the straight flange tof the matches. A plurality of separate tool holders 34b are mounted on the cross piece 33. These tool holders 341) are mounted laterally of the tool holders 34a and are secured by means of screws 361) (Fig. 8). Punches 41 are linked to the tool holders 341), which are pressed against the tools 39 by means of leaf springs 42. The punches 41 cooperate with recesses 53b of guide members 53 (Fig. 14) to stamp out the apertures 1 of the match sheets. The cutting edge of this punch is of a crosssection as required for stamping out the apertures 1. In the downward direction the cutting edge of the punch projects considerably beyond the stamping blade, so that the slit along the flangs t is only effected at the end of the stamping stroke, a slit t for the match flanks being stamped simultaneously with an aperture 1, for the preceding pair of matches.

Underneath the pairof feed rolls 30, 31 between the side shields 32 a supporting yoke U is arranged to the upper edge of which the bearing plate 40 is secured over which the webs B of material are passing. Below each web of material a rectangular aperture 40a is provided in the bearing plate through which the counter roll 31 is adapted to bear against the web B of material, while the feed roll 30, which extends the full width of the machine and is provided above each web of material with a ribbed circumference for driving engagement with this web, bears against the webs of material from above. The drive of the feed roll 30 is effected by means of a ratchet wheel 43 which cooperates with a pawl 43a which is linked to an arm 44 and held in engagement with the ratchet wheel 43 by means of a tension spring 45 attached with one of its ends to the yoke U. The arm 44 is swingably arranged on a pin fixed on the side shield 32 and carries at its free end a roller 46 which cooperates with a cam disc 47 on the main drive shaft W. The cam disc 47 effects via the ratchet wheel drive 43, 43a the required rotational displacement of the roll 30 for executing the feed after each down stroke of the stamping tool. The rolls 10 are rotated continuously from the shaft W by means of linkchains and spur gears, and therolls drive the conveyor band 6 for bringing on the webs B of material. The counter roll 31 for each web of material is mounted in a sliding member 48 (Fig. 10) which is guided to be'displaceable in the vertical direction in a vertical slot of the yoke U and pressed upwardly by means of a tension spring 49 attached with one of its ends to the yoke .U,an adjusting nut 50at the lower end of the sliding member serving for limiting the .throw of the same.

For guiding the webs of material at the entrance to the feed rolls and the stamping device, guide ribs 51 are secured .to-the bearing plate-40, between each two adjacent webs B of material. Forked guide tongues 52 (Figs.,10 and 13) ;.are connected to ribs 51 and bear againstthe webs B of material and extend on both sides of the related guide ribs to the underside of the feedroll 30. Underneath each web of material to the rearward edge of the bearing plate a slightly down'' wardly deflected stirrup 56 is connected; which serves for guiding the web towards the upper side of the bearing plate 40 in case the web should sag.

Each web of material is guided by a guide member 53 (Fig. 14) which is provided with a longi tudinal slot 53a through which the web of material is passed and which, as'aforesaid, is formed at one end with the recess 53b, corresponding in crosssection exactly to the profile of the cutting edge of the punch, for guiding the latter. In front of the bearing plate 40 a vertical guide plate 54 is arranged and the stamping blade 39 is on one side guided between an extension 55 of this guide plate and the front side flank of the guide member 53. The extension 55 is secured to the guide plate- 54 by means of ribs 55a disposed in front of each stamping unit and serving at the same time for guiding a holder 57 of the cutting blade.59 for serving a completed match card. The holder 57' is adjustably mounted in a sleeve 58, with itslower end (Fig. 10), the sleeve being pivotally mounted by means of a pivot pin 59a in a trans-. verse tilting member 60. The tiltingmemberfio extends the full width of the machine frame and is revolubly mounted on journals'oL'. A tension spring 62 connected at one end to the tilting member and at the other end to a lower extension 58a of the sleeve holds the cutting blade pressed against the guide plate 54. The tilting member 60 is provided with an arm 60a which extends in the downward direction in the path of a two. armed lever 63, 64. The latter is rotatably mounted on a shaft 65 (Fig. 8) and its lower arm carries a roller 66 cooperating with a cam disc 67. A- tension spring 68 anchored at one end in the machine frame maintains the roller 66' in bearing contact with the cam disc 67. On each full revolu-- tion of the cam disc 67, which is completed while the cross-piece with the tools performs ten working strokes, the double armed lever 63, 64 effects a rocking motion of the tilting member 60 and the latter a stroke of the cutting blade 59, whereby the stamped match cards are severed along the line Tin Fig. 1e.

The Figs. 17 to 22 illustrate stacking devices for the reception of the definitely stamped match cards.

' In the Figs. 17 and 18 the stamping device of the match-making machine is illustratedby showing all the parts that are necessary for a good understanding of the device. The stampingdevice, in which, as above-described, the completely,

stamped match card B1 is periodically severed. by the cutting blade 59 from the web B of material intermittently advanced by the feed rolls 30, 31, is provided with side shields 32. At the front edge of the side shields 32 in bearing brackets 32a the shaft of a transmission drum 68 is mounted. The transmission drum is provided along its width with twelve sections corresponding to the number of webs of material to be worked and each section is subdivided by sheet metal partitions in chambers each of which receives a severed match card B1. For moving the transmission drum a ratchet wheel drive is provided, a two armed lever '72, 73 being arranged on one of the side shields 32, the one arm '73 of which carries at its free end a guide roller engaging a cam disc '76, while to the other arm of the lever a pawl '71 is linked which cooperates with the ratchet wheel '70. A tension spring '74 attached at one end to the side shield holds the roller on the arm '73 pressed against the related cam disc and the operating pawl '71 is maintained in engagement with the ratchet wheel '70 by means of a tension spring '75. Immediately after each time a match card has been severed, the described ratchet mechanism turns the transmission drum through the extent of one unit of division so that the match cards of a transverse row, which in the mean time were advanced by the feed means for the webs again rendered operative, are gripped by the drum and carried off in the direction of the arrow in Fig. 17. Underneath the transmission drum between the brackets 32b of the side shields twelve conveyor bands '77 are arranged which are passed over rollers '78, '79 and the upper. portions of which form together with the vertical longitudinal walls twelve stacking trays for the match cards. Concentric with the circumference of the drum above the conveyor band a comb 81 is arranged, the tines of which guide the match cards during their travel through the forward lower quadrant of the drum and which ends at a chute 82 to which the match cards pass over through slots 81a in the comb to slide down on the chute to the conveyor bands '77. Through guide slots in the chute 82 pushers 83 project forwardly which are operatively connected to a reciprocating pusher holder 84 in the form of a bar and which by means of the reciprocating motion imparted thereto push the match cards as they slide down in front of them forwardly so as to stand up against the stack S. Thepusher bar 84, is carried by two, levers 85 which are secured to a shaft 86 extending between the brackets 327), To the shaft 86 is also connected a lever 8'7 which carries at its free end a roller cooperating with a cam disc 88, so that the lever 85 is periodically rocked and the pushers 83 advanced. On the shaft 86 is further carried a lever 89 to which a pawl 90 is linked which is held in engagement with ,a ratchet wheel 92 secured to the'shaft 78a of the roller '78 by a counterweight 91 and which effects the advance movement of the conveyor bands '77. Underneath each conveyor band '77 a plate 93 is arranged which serves as'a support.

In the Figs. 20 to 22 a variant construction of the stacking device is illustrated. The stamping device shown in these figures inclusive of the cutting blades 59 is equal to that represented in the Fig. 20. In front of the cutting blades 59 twelve conveyor bands 95 are disposed, the rearward guide roller 96 of which is of a relatively small diameter to permit the bands to approach the cutting blades. for receiving the severed match cards as closely as possible. The conveyor bands 95 which pass over a supporting plate 98 run on forward guide rollers 97 to deliver the severed match cards B1 forwardly to the said forward guide roller. Ahead of these forward guide rollers which are mounted on brackets 32b, connected to the side shields 32, on a shaft 99 transfer levers 100 are fastened which are in the form of an arcuate portion 100a merging in an extension 1007), the bottom plate of the stacking trays 101 for the webs of material extending tangentially to the arcuate portion of the respective lever arm and the entrance ends of the trays being closedby a sliding plate 104 which is periodically lowered for the length of a match card. Each transfer lever 100 consists of two sheet metal parts which are connected to the shaft 99 on both sides of the related conveyor band or transmission roller 97 respectively. 7 Moreover, on the shaft 99 a downwardly extending arm 102 is secured which for periodically rocking the shaft and the transfer lever is engaged by a connecting rod 103. Each sliding plate 104 is secured on an upstanding rod 105, the middle portion of which is offset to avoid interfering with the shaft 99. The rods 105 are connected. to a common transverse bar 106 which is mounted in two levers 107 secured on a shaft 108. For the purpose of reciprocating the slides 104 a periodic rocking motion is imparted to the shaft 108 by means of a lever 109 fixed on shaft 108and pivotally connected to a connecting rod 110, a reciprocating motion being imparted to said rod by any suitable means not shown in the drawings.

1e match cards brought on by a conveyor band 95 for one web of material slide over the forward guide roller 9'7 down on the transfer lever 100 in the position of the extension 1001) of the same asindicated in chain dotted lines in Fig. 22. At the same time the slide 104 is lowered and immediately afterwards the arm 100 rocked tothe left in this figure, thus showing the match card in the stacking tray whichit enters in upstanding position so as to line up with the other stacked cards in which position'it is held by the slide 104. which was again raised in the mean time. In order to provide for a transfer of the match cards entirely free of disturbances the rearward edge of the bottom of the stacking tray is downwardly deflected in an arc concentric with the shaft 99.

This arrangement offers the advantage that defective or cracked match cards are readily detected andremoved, thus avoiding scrap among the delivered goods.
