WORKING METHOD AND MACHINE FOR THE MANUFACTURE OF STICKING PAPER- STRIPS PROVIDED WITH LOOP HANDLES FOR CARRYING PURPOSES Oscar Kind, Rodenkirchen-on -the-Ithine,
' Germany Application July 2.9, 1935, Serial No. 33,916
In Germany August 4; 1934 25 Claims.
The present invention rel-ates to amethod and machine for the mechanical production on a large scale of sectional gummed or adhesive paper strips, the s'ectionsof which are provided with loop handles and designed as carrier means to be secured on packages of more or less weight such as are carried byhand, the said carrying means also functioning to secure the paper wrapperof such packages.
, Paper strip carriers of this type are manufactured, in contradistinction to the ones previously known and made singly by hand, in accordance with the present invention, byrmechanic-al means in uninterrupted operation and succession in the formpf .strips of any desired length, and, similar to the common gummed paper strips,
are made up in the. form ofrolls andare arranged ready for use in suitably constructed delivery housings, for thefsimultaneous withdrawing of the strips and the moistening of the gummed surfaces of the strips. V h r The working method, as well as the mechanical means 7 which comprise in the main the nature of the present invention, provide for such a construction of the several mechanical parts cooperating' in the production of the carrier strips, that thestrip of whioh the handle is made consists of a more'orless narrow, flexible, so-called bast strip which is attached along the approximate middle of the gum coated surface of a wider paper strip in such a way that a space is 'pro'videdfon the latter along which the first strip forms a loop substantially longer than said space, by passing the narrow strip from the gummed side of the wide strip through two holes provided for this purpose to andbeyond the outer or ungummed surfaceof the wide-paper strip. 7
1In accordance-withrthe operating method on which the present invention is based, such carrier -means', attachable'to apackage by their gummed I surfaces, .are made by preparing andconveying 'a gummed paper strip, of any length, together with a handle strip, with the ends arranged so that both strips may be unooiled from'supply rolls in such a manner that the handle strip .is moved so much faster than thegu nmed paper strip that it provides the lengths necessary for the making of: the loop handles. During theforward movement of the gummed paper strip, the gummed surface of the latter'is moistened along the middle between holes. punched in the paper strip for the passage of the handle strip through the gummed paper strip in a length equal to the, a length of the handle strip .and thus made to stick connecting sections-of the handle strips- (Cl. 93-1) lying between the loop handles by pressure upon j the moistened gummed portion. V The holes serving for insertion of the handle loops to the surface left free of gum of thesaid fork may serve, at the sametimafor effecting a rapid movement of the supply roll for the handle strip in order to provide the required length of the handle strip used in the formation of the loop.
After the two strips have been connected intoonegummed paper strip provided with loop handles, cross holes are punched between the individual sections provided with handles, preferably during the forward motion of said gummed paper strip, or in the intervals of this motion. By means of these holes, the handle strip is weakened to facilitate the ripping off of individual sections of V the gummed strip for use.
With the foregoing and other objects in View, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fullyset forth and 1 claimed. i
'In describing the invention in detail, reference .Will be had to the accompanying drawing forming part of this application, wherein like characters denote corresponding parts in the several views, and in which- 7' Fig. 1 of the drawing shows the operation of f orming the strip and illustrates successive sec-" tions of the strips and the steps of uniting them and forming the loops. p
.Fi'g. Zshowsdiagrammatically in longitudinalsection the, main parts of a machine for carrying out the method shown in Fig. 1. r V
The illustration of the operation according to- Fig. 1 shows the paper strip I, the top surface of which represents the gummed surface in the. .above view. The part of the 'paper'strip lying between the marks I and II hasnot as yet been operated, on, the longitudinal distance between the above marks equalling the length of each strokaflby which the paper stripis advanced. Between the marks II and III the paper strip I has been provided with two punched holes 5 between which the paper strip is cut as at 6. The spaces 4 of the gummed surface of the paper strip in the middle and next to these punched holes have been moistened. The handle strip 3 coming from above is conveyed to the moistened paper strip I. Before it is attached to the surface, it runs over said surface at a little distance from the latter, enters a hole 5 on the section III--IV to pass through to the bottom side where it forms a loop I, whereupon it returns through the second of the two holes to the top surface of the paper strip and is attached thereto by pressure.
The part of the handle strip lying along the gummed surface between the holes 5 is also pressed to the gummed surface 5 in the middle of the paper strip and thus made to stick, after the loop 1 is made. At the ends of two handle strip sections (at the mark IV) a cross-hole 8 is punched through both strips in such a Way that the fixed handle strip 3 has been completely out through and also the paper stri l for the greater par-t of its width. On the paper part lying between the section marks IV and V, the carrier device is shown completely formed; however, a fold may be made in loop I, as shown in dotted lines between IV and V, for the sake of facilitating the coiling of the strip.
The machine for carrying out the manufacturing process consists of a table plate 9, on the upper surface of which a tool supporting device It) is arranged and is movably connected with the table 9 by means of guides ll passing through suitable openings in the plate 9. This tool support is connected with a pair of stroke eccentrics l4 arranged on the driving shaft it by means of two guide bolts H and connecting rod H2 in such a way that the device I0 is moved by this shaft.
The tool supporter Ill is fitted with a pair of dies l5 and a cutter l6 engaged with the respective counteracting cutters on the table 9. In addition to the foregoing, the tool supporter is provided with a pressure ledge l8 above an elastic pressure cushion ll inserted in the table surface.
A recess 20 is arranged in the table plate 9 between the beforementioned pressure ledge and another pressure ledge H) of similar construction in such a way that the two teeth 2! of a thrust fork 22 can enter said recess.
The fork is supported by the guiding slide 23 and is held in a lifted position by a lever 2 to which it is connected, by means of pins 26 on the fork 22 engaged with slot-shaped holes 25 in the lever 24 by a tension spring 2? having its ends secured to the lever and to a suitable bracket. The lever 24 and its axis of rotation 28 are supported by the tool-supporter it. Opposite this bearing a counteracting arm 25, as shown in the drawing, is formed on the lever at an angle thereto so that, at its end, a catch-nose Si) is formed. In the path of this catch-nose a catch 3| is provided carried by a perpendicular guidebar 32, which by the action of the spring 33 is pressed downward in such a way that the lower end of the guide-bar 32 rests on the surface of the table 9. The catch 3! yields against the action of a spring (not shown), allowing same to pass underneath the nose and raising it by the upward movement of the catch 3i until the release position is attained.
Adjacent the pressure ledge !9 on the bottom surface of the tool-supporter it) another die 34 is provided; a folding plate 35 being attached to the end of the supporter ii) by means of a bracket 35a and springs 35b.
A pair of rollers 35 arranged on the left side of the front edge of the Working table 5 effects the guiding of the paper strip I when it enters the machine. Between said pair of rollers 36 and the front end of the tool-supporter IS a moistening device is arranged consisting of a brush 3! and conveying means 38 for the liquid. This moistening appliance is supported to swing on a horizontal axle 39 and is provided with a leverarm 39 ending in the path of a catch 40 attached to the tool-supporter II].
On this side of the machine the conveying means for the bast strip 3 has been arranged. The conveying means consists in the main of a pair of conveyor rollers 4| driven by the shaft 13 through a friction coupling (not shown in the drawing), in such a way that the paper strip is passed through between. said rollers. In a nearly perpendicular direction above the entering point 65 of the strip on the tool-supporter, said strip is conveyed over a guide roller 42, arranged at the end of the lever 43, the other end of which carries a weight. The end of the brake band 45 is attached to the lever arm at a point between its axis of rotation 44 and the roller 22 allowing cooperation with a brake disk 46 carried by the upper roller 4 i.
The arrangement necessary for the progress of the paper strip is driven by the shaft I3. The means provided for it is a driving mechanism consisting of a hub d? and the crank loop 48, acting through the aid of the connecting rod 49, the lever 50, and a connecting rod 5i, the length of which is preferably adjustable, upon the end of a lever jaw 52 pivoted to and moving the stroke slide 53 to and fro. Said lever jaw 52 is fitted preferably with a roughened roller clamp 53 which, as the jaw 52 moves in one direction, is pressed against an elastic support carried by the slide 53, and when the jaw 52 moves in the other direction, is kept in a raised position by the tilting of the jaw 52 to allow the unobstructed passage of the paper strip I.
Another cam 54, also arranged on shaft l3, operates with the aid of the double armed lever 56 swinging around its bearing pivot 55, an auxiliary roller clamp 5'! which holds the paper strip tightly during the back travel of the stroke slide 53.
The operation of the device is as follows: During the continuous rotation of shaft l3 in the right hand direction (after starting from the position shown in Fig. 2), the tool-supporter lfl is first moved into its raised position (shown in Fig. 2 by dotted lines) by the action of the eccentrics M, the blades l2 and the rods ll. At this time, shortly after the punching tools I 5, l5 and 34 have moved up with the supporter II] from their counteracting cutter recesses, the feeding means for the paper strip starts, and by means of the linkage E9, 58, 5|, motion is transmitted from the cam 47 and slide 48 to the paper strip in such a way that the roller clamp 53', arranged on the end of the lever 52 opposite the end connected to the rod 5!, is pressed against its elastic support, so that the paper strip which lies between said slide 53 and the roller 53' is therefore carried along and moved forward to an extent equal to the movement of the slide 53.
During this forward stroke, the auxiliary clamp 5i has been held in open position by the action of the lever 56 as it is moved by the cam 54 also fixed on shaft l3. This clamp 51 grips the paper strip and a handle strip to form handles on the gummed paper strip, a table, a tool holder mounted above said table to reciprocate vertically to and from said table, a driving shaft, means operatively connecting said shaft and tool holder to reciprocate the latter, feeding means actuated by said shaft for imparting a step-by-step movement to a gummed paper strip extending along said table beneath the tool holder with its gummed side up, a feeding device for a handle strip operated in unison with said feeding means to feed a handle strip along the upper side of said gummed paper strip in successive slack portions, punching means carried by the tool holder to cut a longitudinal slit along the center line of the gummed strip as the paper rests beneath the tool holder, pusher means actuated by and supported on the tool holder and engaging the handle strip to force slack portions thereof through said slits, means to cause adhesion of the handle strip between said slits to the gummed strip, other punch means carried by the tool holder and punching the adherent portions of the handle strip and gummed strip between said slits to sever the handle strip and partially sever the gummed strip, and clamping means actuated by said shaft and cooperating with the table to clamp the strips against movement during the descent of the tool holder.
