8 Claims. (Cl. 1541.6)

, The present invention relates to an improved machine for manufacturing tying devices.

The tying devices with which the present invention is concerned comprise a strip of paper doubled lengthwise along its longitudinal center .line about a length of de formable Wire extending the length of the device. The folds of the paper are glued to one another and to the wire by a suitable adhesive. The machines which have heretofore been proposed for manufacturing such items are unduly complicated and are capable of producing tying devices only at a relatively low rate of production.

It is a principal object of the invention to provide a relatively simple, fast operating machine for forming such tying devices from a continuous strip of paper and from a continuous length of wire.

It is a further object of the invention to provide a machine having means for printing legends upon one surface of a continuous strip of paper and further means to thereafter fold and glue said strip about a wire to form tying devices of the character described.

Another object of the invention is to provide improved means for drawing strip material through a machine.

Still another object is to provide improved means for segregating and counting the tying devices manufactured by the machine.

Other objects and advantages of the invention will become more apparent hereinafter.

In accordance with an illustrated embodiment the present invention comprises a machine upon which are mounted a roll of wire and a roll of narrow paper strip. The paper and wire are simultaneously drawn from the rolls, the paper passing first through a printing means which imprints trade-marks or legends upon one surface of the paper and then passing through a glue applying means which applies glue to the opposite surface of the strip. The paper strip and wire are then simultaneously fed through a folding device which folds the paper strip along its longitudinal center line and about the wire. The folded strip and wire are trained about a relatively large wheel or drum and are held in frictional engagement with the surface of the drum which is driven by a suitable motor whereby the drum acts to draw the strip and wire through the machine. The folded strip is led from the drum through a severing device which severs individual tying devices of predetermined length from the end of the strip and which devices are then passed through a segregating and counting device which collects groups of predetermined number of the tying devices.

For a more detailed description of the invention, reference is made to the accompanying drawings and the description thereof.

Fig. 12 is a perspective view of a modified form of tying device which is adapted to be manufactured upon the machine of the invention; and

Fig. 13 is a cross-sectional view similar to Fig. 7 showing the construction of the drawing wheel rim as modified for the manufacture of tying devices as shown in Fig. 12.

Referring first to Fig. 1, there is shown a tying device 4 as produced by the machine and method of the present invention. The tying device 4 comprises an elongate strip of paper 5 or like material which is folded along its longitudinal center line about a wire 6 extending lengthwise of the device. The opposite folds of the paper are glued together by a suitable adhesive indicated at 7 so as to secure the wire 6 therebetween. The outer surfaces of each of the folded portions are adapted to have the users trade-mark printed thereon as indicated at 8 or to have advertising messages or the like printed thereon.

Referring next to Figs. 2 and 3, the machine of the invention comprises a frame 9 upon which is supported a supply roll 10 of paper web or strip 11 having a width substantially twice that of the finished tying device 4. Means are provided on the machine for printing upon each of the longitudinal half portions of one surface of the strip 11 a repeated pattern of the trade-mark or legends 8. As shown, from the roll 10 the strip 11 is fed over tension rolls 12, 13, 14 and thence between a printing roll 16 and Kinton bar 15 mounted adjacent one end of the machine which for convenience will be termed the rearward end. A supply of ink for the printing roll 16 is maintained in a container 17 and transferred to the roll by inking rolls 18, 19 in a well known manner. Obviously with a single printing roll only a single color may be applied to the strip 11, but the arrangement shown may be varied and additional printing rolls supplied if multicolor printing of the strip 11 is desired.

After the legends 8 have been printed on the strip 11, it is led over a series of

guide rolls

20, 21, 22, 23 to glue or adhesive applying means positioned at the opposite or forward end of the machine. The printing means and the glue applying means are preferably located at opposite ends of the machine so that the transit time of the strip from the printing means to the glue applying means will be sufliciently long to permit the inked legends to dry. Supported on the frame 9 is a glue pot 24 in which is rotatably mounted a transfer wheel 25 for transferring the glue or adhesive to the strip 11. The strip 11 is maintained in contact with the transfer wheel 25 by a roll 26 about which the strip is trained with the printed surface of the strip facing the surface of the roll. A doctor knife 27 (Fig. 4) is preferably provided to spread the glue 7 over one of the side portions of the strip, the knife being arranged so that a relatively heavy film of glue is distributed adjacent the middle of'the strip while a relatively thin film is spaced towards the edge, the purpose of which will become more apparent hereinafter.

Mounted on frame 9 is a motor '38 which is drivingly connected to a jack shaft 28 by a belt 29, the jack shaft being connected to drive the various moving vparts of the machine as will be described. A hand wheel 31 is provided on the jack shaft 28 to permit manual movement of the various operating parts in adjusting the same. The transfer wheel is driven from the jack shaft 28 by a chain 30 trained over suitable sprockets.

From the glue applying means the strip is led upwardly past a pair of

guide fingers

33, 34 and then through a folding cone 35 supported upon a vertical frame panel 32. The folding cone 35 shown in detail in Figs. 5 and 6 provides means for folding the strip 11 substantially along its longitudinal center line and comprises a conical member having-a relatively wide mouth 36 into which the flat strip is fed. The cone 35 tapers from the mouth 36 to a slitlike outlet 37 having a'length substantially equal to half the width of the strip '11 whereby the walls of the cone engage the strip and cause it to fold upon its'longitudinal .center line as the strip is drawn through the cone. The legends 8 will appear .on each side of the folded strip.

Supported on the frame upright 42 is a roll 43 of wire 44, the roll being mounted substantially beneath the glue .pot .24. The wire 44 is trained over a pair of

pulleys

46, 47 suitably supported at the forward end of the machine,

and from the pulley 47 is led through the folding cone 35. 'The wire 44 is guided into the folding cone adjacent the adhesive coated surface of the strip 11 and pulled through the cone simultaneously with the strip by means to be next described whereby the strip is folded about the wire as shown in Figs. 5 and 6. Preferably the wire 44 is formed of soft iron or other deformable material so that the ends of the tying devices 4 may be easily twisted together when they are put to use. Preferably also the wire 44 is galvanized or otherwise suitably treated to render the same rustproof.

As stated above, means are provided for simultaneously drawing the strip 11 and wire 44 through the .machine. Mounted on the frame panel 32 is a drum wheel 50 of relatively large diameter and formed with a relatively wide peripheral surface or rim 51. 'The wheel 50 is mounted upon a shaft 52 which is driven from the jack shaft 28 by a chain 53 and gears 54. The folded strip which for convenience is designated by the numeral 55 is trained about the wheel 50, means being provided to .hold the folded strip 55 in frictional engagement with the surface of the wheel over a substantial portion of the circumference thereof. The last mentioned means comprises a .plurality of

small rollers

56, 57, 58 and 59 mounted to be biased into engagement with the periphery of the wheel.

Since the mounting arrangement of each of the rollers .is t

substantially the same, only the mounting arrangement of .one of therollers, 59, will be described in detail. The roller 59 is mounted on one end of a lever arm 60 which is pivotally mounted at-a medial point 62 thereof upon the frame panel 32. A coil spring 63 is connected between the opposite end of the lever 60 and the frame panel 32 in such manner as resiliently to bias the roll 59 towards the periphery of the wheel 50 whereby the folded strip 55 is held inpressurable engagement with the wheel rim. Thus, as the wheel 50 revolves the paper strip 11 and wire 44 will be drawn from the rolls of the same and through the machine. 'Since the strip 55 is held against the wheel over a considerable portion of its circumference, no slippage will occur between the wheel and strip. The outermost fold of the strip 55 as it passes about the wheel 50 is firmly held against the innermost fold by reason of the longerpath of 'the outer fold whereby to facilitatethe gluing process.

Provided between the folding cone 35 and the'drawing -wheel'50 are a'pair of offset

rollers

65, 66 rotatably and between "which the folded strip '55is drawn-to crease the fold thereof.

Referring now to Fig. 7, the rim 51 of the wheel 50 is formed with a relatively deep rectangular, circumferential groove or notch 70 therein and a parallel, small, semicircular circumferential groove or recess 71 spaced from the notch 70 bya distance substantially equal to the distance the wire 44 is spaced inwardly of the open edge of the folded strip 55. The folding cone 35 and .the wheel 53 aligned on the machine so that the folded strip "55 passes onto the wheel 50 with the open edgeof the strip immediately adjacent the edge of the notch 70 and with the wire 44 juxtaposed the recess 71. Any adhesive that is expressed from the open edge of the strip 55 will flow into the notch 70 and will not spread over the surface of the rim 51 as would occur if the notch 70 were not provided therein. Should glue spread over the portion of rim engaged by the strip 11 the operation of the machine would be hampered by the resulting adhesion of the strip to the rim.

The purpose of spreading the glue in a heavy film toward the center of the strip 11 and a light film toward the edge is two-fold. A light film of glue near the edge of the strip 11 reduces the amount which might be expressed out from between the folds, the advantage of which is apparent from what has been described above, and the heavier film toward the center is desirable to supply sufiicient glue completely to cover the wire 44. Preferably the wire guide pulleys 46, 47 are in substantial alignment with the plane defined by the recess 71 so that the wire will feed thereto in a straight line, the cone 35 being so positioned that the slot 37 extends substantially equidistantly on opposite sides of the path of the wire 44 whereby the wire will be substantially centered laterally of the folded strip 55.

So that the machine may be more easily adapted for forming tying devices of various widths, additional recesses may be provided for receiving the wire of wider folded strips as indicated at 72.

In passing about the wheel 50, curvature is imparted to the wire 44. Means are provided to remove or reduce this curvature comprising a pair of belts 75, 76 arranged with a pair of adjacent flights between which the folded strip 55 is passed as it leaves the wheel 50. The uppermost belt 75 is trained about a pair of pulleys 77, '78 rotatably supported in a suitable manner upon the frame panel 32. The lower belt 76 is trained about a plurality of

pulleys

79, 80, 81, 82, 83 and 84. The

pulleys

80, 81, 82, 83 and 84 are rotatably mounted in a suitable manner upon the frame panel 32. The pulley '79 is drivingly mounted upon the shaft 28 and is driven at the same peripheral speed as the peripheral speed of the wheel 50 whereby the velocity of the flight of the belts 75, '76 will be the same as the peripheral speed of the wheel '50. The pulley 84 is offset with respect to the pulleys 77, 78 of the uppermost belt 75 so that the adjacent flights of the belts 75, 76 are reversely curved in respect to the curvature of the folded strip 55. Thus, as the strip 55 passes between the belts 75, 76, at least a portion of the curvature imparted to the same by the wheel 50 will be removed therefrom.

Means are provided for severing tying devices of predetermined length from the end of the folded strip 55 and which means will now be described. Referring more particularly to Figs. '8 and 9, mounted on the frame panel 32 just below the path of the folded strip 55 as it is discharged from the belts '75, 76 is a shearing block 87 immediately above which is mounted a guide bar 88, the strip 55 being fed through a slot between the guide bar and the shearing block. Mounted immediately adjacent the shearing block 87 and guide 'block 83 is a reciprocating knife 89 which reciprocates in a plane normal to the path of the folded strip 55. The knife 89 is driven bya pair of meshed 'gears' 90, 91

mounted upon

shafts

92, 93, respectively. The shafts are supported from the frame panel 32 in suitable bearings indicated at 94 and are drivingly connected to the jack shaft 28 by a chain 96 and a gear unit 97 (see Fig. 3). The knife 89 is pivotally connected to the gear 90 by a pin 99 and is connected to the gear 91 by a pin 100 which protrudes through a slot -101 formed in the shaft of the knife. It will be seen from Fig. 8 that as the

gears

90, 91 are driven in the direction of the arrows, the knife will be caused to reciprocate downwardly past the shearing block 87 and will then be drawn backwardly and upwardly out of the path of the folded strip 55. By reason of the connection of the knife to the meshed gears in the arrangement shown, the knife will tilt in respect to the horizontal as it reciprocates whereby the blade portion of the knife will move downwardly past the shearing block at a relatively rapid rate of speed. The period of reciprocation of the knife 89 is adjusted with relation to the speed of the wheel 50 so that the tying devices 4 of desired length will be severed from the end of the strip 55.

It is not practical to attempt to remove all of the curvature from the strip 55 which was imparted thereto by its passage over the wheel 50 before the tying devices 4 are severed from the strip. Hence a further set of straightening belts are provided on the machine to remove any vestiges of curvature remaining in the individual tying devices 4 after they are severed by the knife 89. Referring now more particularly to Fig. 2, a pair of vertically juxtaposed

belts

105, 106 are mounted immediately adjacent the knife 89 and are positioned so that the end of the strip 55 is engaged between the belts just prior to the severing of a tying device 4 from the strip. The upper belt 105 is supported on pulleys 107 and 108 which are rotatably mounted upon a vertical subfrarne plate 109. The pulley 108 is mounted on a shaft 114 which extends through the plate 109 and is driven by a chain 115 drivingly connected to a shaft 116 driven from the jack shaft 28 by a chain 117. The lower' belt 106 is mounted upon a pair of pulleys 110, 112, also rotatably supported upon the subframe plate 109. The lower belt 106 passes over a pulley 111 which is adjustably mounted in asuitable manner on the plate 109 and is positioned to form an arched path of travel of the adjacent flights of the belt whereby to bend the tying devices 4 reversely in respect to the curvature they possess as they are fed between the belts whereby the tying devices will be discharged from the belts with substantially all of the curvatur'e removed therefrom. It is preferred that the tying devices be straight to facilitate packaging and handling thereof. The

belts

105, 106 preferably are driven at a slightly faster rate of speed than the belts 75, 76 whereby they apply a certain degree of tension to the strip 55 as it passes over the shearing block 87, facilitating severance of the tying device by the knife 89.

Means are provided on the machine for segregating the tying devices 4 in groups of predetermined number. Referring now to Figs. and 11, mounted on the frame 9 forwardly of the

belts

105, 106 is an elongate drum 118 having a plurality of longitudinally extending compartments formed therein. The drum is shown as formed with six

compartments

119, 120, 121, 122, 123 and 124, though any number of compartments may be provided as will be apparent. The drum is rotatably supported on a shaft 125 and is positioned so that the uppermost compartment of the drum will receive the tying devices 4 as they are discharged from between the

belts

105, 106. The drum is drivingly connected to the shaft 125 by a helical spring 126 whereby the motion of the drum may be arrested though the shaft 125 continues to rotate. The shaft 125 is driven by gears 136 which are drivingly connected to the drive means of the shearing mechanism by a shaft 127, gears 128 and a chain 129. By changing the gear ratio in the driving connection, the relation between the severing mechanism and the counting mechanism can easily be changed.

Projecting from one end of the drum are six

pins

130, 131, 132, 133, 134 and 135, which are spaced equally angularly apart about the axis of the drum. Mounted upon a frame upright 137 adjacent that end of the drum is a catch lever 138 having a rounded toe 139 formed on its lower end. A spring 140 is connected between the upright 137 and the upper end of the catch lever 138 and is arranged so as normally to retain the lever in position with the toe 139 in the path of travel of the pins. The lever 138 is adapted to engage the pins successively as the drum rotates and to arrest the motion of the drum so as to hold the drum with one of the compartments thereof positioned to receive the tying devices discharged from the

belts

105, 106. Referring to Fig. 10 the drum 118 is shown as arrested with the compartment 119 positioned uppermost for receiving the tying devices 4 therewithin. The spring 140 is sufficiently strong to overcome the biasing force of the spring 126 which normally would cause the drum to rotate simultaneously with the shaft 125. Positive drive means are operatively provided on the drum and shaft to cause the drum to rotate after it has been arrested a predetermined period of time. Fixedly mounted on the shaft is a pawl 142 which extends between a pair of the

pins

135, 130. When the drum 118 is rotating freely with the shaft 125, the pawl 142 is positioned adjacent the lagging pin as shown in solid lines in Fig. 10. When the drums motion is arrested by the catch 138, the pawl will continue to advance with the shaft and after a predetermined period of time will engage the pin 130 as indicated by the dotted lines 143 in Fig. 10. When the pawl 142 engages the pin 130, the positive driving force exerted upon the drum will cause the pin engaged by the lever toe 139 to ride around the toe, the spring permitting the lever 138 to pivot to permit this action. As soon as the drum is relieved of the restraint placed thereon by the lever 138, the spring 126 will cause it to advance to its normal position in relation to the shaft whereby the next succeeding pin 133 will be engaged by the toe 139 and the pawl 142 will be positioned between the

pins

135, 130 as shown in the solid lines of Fig. 10. The compartment 124 will be advanced to the uppermost position as the drum rotates and the compartment 119 will be rotated to the position of the compartment 120 as shown in Fig. 10, whereupon the tying devices 4 collected in compartment 119 will fall out upon a table or other collecting means (not shown) for bundling or packaging as desired. Inasmuch as the speed of the shaft 125 is synchronized with the shearing knife 89, the number of tying devices 4 collected in each compartment will be the same or substantially so.

A modified form of tying device which the machine of the invention may be easily adapted to manufacture is illustrated in Fig. 12. The tying device 150 comprises a pair of superposed narrow strips of

paper

151, 152 between which isglued a reinforcing wire 153. Such a device may be manufactured by providing two rolls of paper strip upon the machine of the width of the finished device and superimposing a strip from one roll upon the strip from the other roll while feeding a wire therebetween, at least one of the strips having an adhesive coated thereon. The manner and means of accomplishing this will be well known to those skilled in the art. If desired, one or both of the strips could be printed upon their outer surface as is the paper strip 11 in the machine of the first described embodiment.

After the two strips of paper are brought together about the wire, the strips are fed flatwise upon a drawing wheel 154 substantially similar to the drawing wheel 50, but having a rim 155 modified as shown in Fig. 13. The rim 155 is formed with a pair of relatively deep, rectangular circumferential

groovesor notches

156, 157 spaced apart a distance equal to the width of the

strips

151, 152

and between which notches the strips are fed whereby the'edges \of the :strips are adjacent the edge of the corresponding notch. Any adhesive expressed from between the strips 151, .152 will fiow into the

notches

156, 157. A :small semicircular groove or recess 158 is provided between the notches 1'56, 157 for receiving the reinforcing wire 153. From the wheel 154 the united strips are fed between the straightening belts 75, 76 and to the subsequent mechanisms of the machine in the same manner as the folded strip 55.
