SCHINENFABRIK-AKTIENGESELLSCHAFT, OF STUTTGART-GANNSTATT,GERMANY DEVICE FOR LAYING OFF SECTIONS CONTINUOUSLY SEVERED FROM WEBS Application filed January 17, 1981, Serial No. 509,347, and in Germany January 22, 1930.

ent, so to say, lose their guidance in the running direction of the paper web and thus become displaced moreor less in relation to one another, so that the correct laying off be-' comes very difiicult. In the case of the mentioned manufacture of printed labels, for instance, the additional trouble arises that the paper web or the individual sections absorb, in consequence of the printing, moisture which in its turn acts upon the fibres of the paper so that the fibres lying stretched in the I direction of travel of the paper web, which corresponds with the running direction of the web in the paper making machine, swell up and thus expand in the'transverse direction so that the width of the individual sections increases or grows. The longitudinal edges of the sections thus do not remain in the direction of travel but move sideways overlapping one anotherslightly.

To overcome the said difficulties in a simple and reliable manner according to this invention, the sections, after having been severed from the web and prior to being laid oflr' into the pile receptacles, are moved apart transversely to the-direction of travel of the paper web. In this way, it is rendered possible to take the special properties of the printed labels or other sections into full consideration andyet to ensure a safe and faultless deposition in pile receptacles arranged side by side. It is even possible to give the individual receptacles a greater width than the width of the sections, so that each section may safely and freely be conveyed into its receptacle.

The invention is illustrated, by way of example, in the annexed drawings.

Fig. 1 is a front elevation of the device,

Fig. 2 is a vertical 'cross-section through Fig. l,

Fig. 3 shows a portion of the device of Fig. 2 in plan, partly in section,

Fig. 4 is a longitudinal cross-section through the special device for separating and laying off the severed sections, and

Fig. 5 is a cross-section through the device shown in Fig. 4.

A characteristic feature of the device is that the' individual sections, while or prior to being severed from the web, pass upon a corresponding number of suitable supports arranged transversely to the feed track of the web and adapted to hold the said sections, and which after the sect-ions have been severed, are moved apart laterally to such an extent as is suit-able'or necessary for the desired lateral separation of the sections, and whichconvey the said sections to the corresponding receptacles for piling them up.

Referring to Fig. 2 of the drawings, A designates, by way of example, a web of paper or cardboard coming from a suitable printing press of any well known construction in which the web is being provided in the known manner with prints corresponding to the desired sections, such as labels. In the present case, the web A shall be subdivided in the device illustrated in the drawin continuously by suitable longitudinal an transverse cuttings into eight sections, each time.

The web A is fed forward in the direction of the arrow shown at the right-hand side of .Fig. 2 through the device.

This is done by means of the feeding roll 21 and the two counter-rollers 22a and 22b. The 'roll 21 is by means of its shaft 21a rotatably mounted in suitable bearings of the two lateral frames 43 and 43a and is continuously rotated by the driving mechanism of the machine, as hereinafter described. The counter-rollers 22a and 221) are supported, by means of their shaft 220, in suitable vertical slots 22d of the said side frames 43 and 43a, vertically displace able and loosely rotatable in such a known manner that they rest by means of their own weight upon the feeding roll 21 and will press the web A upon this roll.

The drive of the device is effected, according to Fig. 1, by the main shaft which is continuously turned by any suitable and known means. 40 is transmitted by a worm 41 fixed upon it to a worm-gear 42 which is loosely rotatable on a bolt 44 fixed in the side frame 43. To the said gear 42 is rigidly secured by suitable bolts the pinion 46 which, in its turn, rotates by means of an intermediate pinion 47 the pinion 48. The pinion 47 is loosely rotatable on a bolt 7 Osecured to the frame 43, and the pinion 48 is fixed upon the shaft 2641, which is rotatably mounted in suitable bearings of the side frames 43 and 43a. A second pinion 49 fixed on the said shaft 26a turns by means of the pinions 71, 72, 73 and 74 a pinion 216 which is secured to the above mentioned shaft 21a of the feed roll 21.

In front of the said roll 21 and counterrollers 22a, 22b there is rotatably mounted in the side frames 43 and 43a the shaft 20a of a roll 20 which is continuously rotated by means of the pinions 20b and 7'5 by the above mentioned pinion 216. The roll 20 is adapted to produce at desired places longitudinal grooves or notches in the web A. For this purpose, the roll 20 is provided at the corresponding places of its circumference in the well known manner with appropriate annular notches with which cooperate knife-like notching discs 76a which are fixed on a shaft 76. The said shaft 76 is mounted vertically displaceable with its ends in ve'rticalslots 7 6b of the side frames 43 and 43a in such a known manner that the notching discs 76a will rest manner of the stationary knife 25 and the with pressure upon the web A.

After having passed between the feed roll 21 and counter-rollers 22a, 225, the web A reaches a suitable cutting device by which the web is cut in longitudinal strips. This cutting device consists in the well known manner of the circular upper knives 23 and under knives 24 which are secured to the shafts 23a and 24a, respectively, supported in suitable bearings of the side frames 43 and 43a. The shaft 24a is rotated by the above mentioned pinion 73 and rotates, in its turn, by means of the pinion 24b; fixed u on the shaft 24a the pinion 236 which is ed upon the upper shaft 23a. By this cutting device, the web A is cut, in the. present case, into eight longitudinal st'ri s. These strips arrive to the device'by which they are cut transversely into the desired sections 1 shown in Figs. 4 and The said device consists in the well known rotating counter knives 26. The stationary knife 25 is adjustably secured by. means of suitable screw bolts 25a upon a transverse bar 256 which is secured at either end to the side frames '43 and 43a. In thepresent case, three upper knives 26 are adjustablysecured The rotation of the said shaft by means of suitable screw bolts 260 in suitable recesses of a roll 26?) which is rotatably mounted with its shaft 26a in suitable bearings of the side frames 43 and 43a. Rotation is imparted to the shaft 260 by means of the above mentioned pinion 48.

During or prior to the transverse cutting operation, the said longitudinal strips of the web have reached with their leading ends a roll or drum '2 which is designed in the present embodiment as a suction drum in such a manner that the said sections 1 will be attracted and held by the said drum. The drum or roll 2 is subdivided into individual sections or parts 2a, in the present case eight sections, which are rotatably and slidably mounted side by side on a hollow shaft 3 which serves as suction pipe. For this purfl j pose, the hollow shaft 3 is connected by means of a sleeve 80, secured to the side frame 43a in continuation of the hollow shaft 3, and the v pipe 81 with a suitable vacuum device of any known kind, such as a vacuum pump which is operated by the driving mechanism of the ma-' chine in the well known manner. A rod 4 mounted in adjustable collars 5 and 5 fixed upon the shaft 3, passes through bores 6 of all the roll sections 2a and thus connects them in such a manerthat they are carried around by the rotation of shaft 3 uniformly in the revolving direction. The rotation of the shaft 3 is produced by the pinion 49 which is secured to the above named shaft 26a and which rotates the pinion 50 secured to a shaft 50a which is rotatably mounted in a suitable bearing of the frame 43. On the said shaft 50a is fixed a second pinion 51 which transmits the rotation by means of the interme-' diate pinion 52 u on the pinion 53 which is secured to the sha t 3. 7

Each roll part 2a is provided with suitable suction openings or nozzles 7 which are in communication with each other by a duct or channel 8. The shaft 3 is further provided with bores 9 so that the suction is exerted at the nozzles 7 through the channels 8 and each label arrivin is attracted by suction and carried along y the revolving r'oll section.

Each section or ortion 2a of the roll is around its circum erence provided with a curved groove 10 engaged by an anti-friction guide member 11 mounted by means of bolt 3 upon a suitable rail 12 which is rigidly fixed to the frame of the machine. The members 11 run withinthe individual grooves 10 so that the drum sections 2a are during the rotation of the drum first moved apart and then returned into their original position. The grooves of the two central roll sections have only a small gradient, whilst the gradient increases in the grooves of the other roll parts' towards the two ends of the roll in such a way that the separation of the roll parts ensures the desired moving apart of the severed, paper sections..

and there deposited in a satisfactory manner.

The front wall 15 of these piles may serve as s'eraper'ffor each label sticking to the roll so that the label is easily detached and dropped into the pile. -The suction action may bemaintained continuously or it may be interrupted just before the labels encounter the front wall 15 in order to facilitate their detachment from the roll. I

- It will be readily understood that the device may be modified in various ways.

The process and device may be also employed for difierently shaped sections produced from a web of paper or other material, for instance for tax or revenue strips of different kinds. It is, furthermore, immaterial whether the paper web is printed prior to be ing severed into sections, and it may be subjected to no surface treatment at all or to a different one, because even if the paper does not absorb moisture, the individually severed pieces of paper inherently have the tendency to move sideways to some extent.

It will be obvious that many other modifications may be made without departing from the spirit of my invention.
