MACHINEFOR. THE PRODUCTION BAGS AND THE LIKE Peter Becker, Dusseldorf, Germany; vested in the Alien Property Custodian Application August 1, 1940, Serial No. 349,179-
In Germany June 18, 1939' 2 Claims. (01. 93-62) When folding bags, pouches, envelopes or the like it is usual to conduct the cut in transverse direction through the roller track of a folding machine, as then the diameter of therollers and also the distance between the rollers can be less great than when the cuts pass through the machine in longitudinal direction.
It is further of great advantage that on one and the same machine smallest envelopes as well as very large envelopes can be produced. In the folding machines of this type as used at present it is usual to distribute on several rollers the tools for folding and sticking the envelope. One or several rollers for pre-folding are arranged and also one or several gumming rollers. These rollers are all of similar diameter, and one revolu-.
tion of the rollers corresponds as a rule to the folding of one envelope. I The size of the envelopes to be made depends on the diameter of these rollers and on the distance between them. The larg est' and the-smallest width of the envelope is process prior to the forming of the transverse fold, and y at Fig. '7 a folding proceeding according to the upsetting process after the forming of the prelim- I inary fold.
as fol-' The operation of the folding'rnachine is lows:
The sucker I (Fig. 5) sucks the lowermost cut of a pile, 2 into the notch of a roller 3. By the cut gets to the roller 5 which feeds the cut in horizontal position to the pair of rollers 6, 1. From I here the cut gets into the pocket .8, where the front edge of the out comes into contact with stops '9. Hereby the cut is upset and forms a loop in front of the rollers l, lllwhich loop is gripped by these rollers and folded to form-a fold. This kind of folding is known. Continuing to move along the guide II the sucker l2 of the duce small .and large bags of larger than the usual difference in size on one machine, for only one single pair of rollers'is constructed astool carrier, namely the pair of gumming rollers. The diameter of these gumming rollers determines the largest bag, whereas all other rollers and their distances are kept very small so that even the smallest possible envelopes can be folded with the same machine. The pre-folding knives are omitted and the folding of the transverse folds can be obtained for instance by upset folding known from the manufacturing of flat bags. in which the transverse folds are adjusted by adjustable stops. v
As this machine works with smaller rollers than was possible up to the present, the machine is of smaller size, more handy and cheaper.
An embodiment of the invention is illustrated by" way of example in the accompanying drawing, l
counter gumming roller l3 sucks-on this cut and conducts it along the gumming element l5 of the gumming roller M to the 'roller IT. The gumming element l5 receives its agglutinant from the glue-mechanism IS. The cut is then fed to the pair of rollers ll, 22 below the guide l8 and thence into the pocket l9, wherein the feeding is stopped by the stops 20. The stops 9,20 are adjustable, so that the transverse folds can be guide at the fold formation (Figs. 6 and 7) At this second pre-folding the cut is turned, so that the bottom-and closing flap 24, 25 of the cut (Figs. 3 and 4) come to the top. This is a great advantage as then a control of the folding of these flaps is ensured. The cut is conducted through the machine only in horizontal position so that the flaps are on top.
1. In a machine ofithe kind described, a set of feeding rolls including a pair of spaced rolls rotating in the same direction and a third roll resting on ,and coacting with each roll of the pair,
a vertical guide for receiving a blank passing between the first and third rolls in one direction and for delivering a blank in position to pass in the opposite direction between the second and third roll, a stop associated with said guide and arranged to stop movement of the blank into said guide prior to the passage of the blank en- ,tirely' in the first direction whereby t6 cause 'a bend to form in said blank for folding between the second and third rolls, a second set of similar rolls, guide and stop, the second guide reing on and coactihg with each roll of the pair, a
