ABSTRACT

METHOD FOR MAKING SUPPLY ROLLS FROM BAG OR SACK CHAINS AS WELL
AS SUPPLY ROLLS MADE ACCORDING TO SAID METHOD

The invention relates to a method for making supply rolls from sacks or bags joined together in web-like bag or sack chains, with thickenings lying at at least one edge region of the bag or sack chains and preferably formed by side folds, hand-les and handle strengthenings. For the solution of the problem, to provide a method of this kind according to which fine and sta-ble supply rolls having a cylindrical form can be made from sack or bag chains having thickenings at their edges, the bag chain is wound on a winding core or winding tube which only extend along the not thickened section of the sack or bag chain or of the supply roll being formed.

METHOD FOR MAKING SUPPLY ROLLS FROM ~AG OR SACK CHAINS AS WELL
AS SUPPLY ROLhS MADE ACCORDING TO SAID METHOD

BACKGROUND OF THE INVENTION

Field of the Invention This invention relates to a method for making supply rolls from sacks or bags joined together in web-like bag or sack chains, with thickenings lying at at least one edge reyion of the bag or sack chains and preferably formed by side folds, hand-les and handle strengthsnings, and also to supply rolls made ac-cording to this method.

escription of the Prior Art When supply rolls toring the sacks and bags are formed out of sack or bag chains, at the sides thereof beads are obtain-ed, if the sack or bag chains have thickenings at their edges, said beads not only impeding the formation of the supply rolls and impairlng latters' stability, but also providing them with an untidy appearance.

5ummary of the Invention It is an ob~ect of the invent1on to provide a method of the kind mentioned here~nbefore, according to which fine and sta- -blQ supply rolls hav$ng a cylindrical form can be made from sack or bag chains having thickenings at their edges.

This problem i8 solved according to the invention by a method of the generic type by the fact that the bag chain is wound on a winding core or winding tub~ which only extend along the not thickened ectlon of the sack or bag chain or of the supply roll being formed. According to the method of the lnvent- -lon, during winding the bead or the beads at the edges are press- ~-ed into the space located between the front sides of the winding . ~
2 ~ 3 ~

cores or winding tubes and the rolls wound thereonto. Since thus the beads at the edges are pressed through towards the inside, cylindrical supply rolls can be formed in spite of thickenings at the edges. For this purpose, the diameter of the winding co-res and of the supply rolls is to be dimensioned suoh that the spaces formed between their front sides are capable of receiving the thickenings pressed to the inside without beads being formed at the edge sections of the supply roll after filling these spa-ces.

For a method for making supply rolls from sack or bag sca-les consisting of a web-like sequence of sacks or bags arranged in overlapping or scale formation, with thickening~ lying at at least one edge section of the sack or bag scale and preferably formed by side foldc or handle.~ or handle hole strengthenings, in which the sack or bag scale is wound onto a winding tube or :
winding core together with two holding straps, the probl~m is :
solved in accordance with the invention in that the sack or bag scale is wound onto a winding core or winding tube extending on-ly along the not thickened section of the sack or bag scale or the supply roll being formed.

A supply roll made according to the method of the i~vent-ion is distinguished according to the invention in that the thickened edge portion or the thickened edge portlons are press-ed into the space between the front side(s) of the winding core or the winding tube and the roll in such a way tha~ the supply roll as a whole has a substantially cylindrical form.

Advantageously a rod is provided extending through the winding core or the wind ing tube along the center line, said rod carrying plates at the end bordering the supply roll. Said pla-tes are used for the support of the front sides of the roll so ~ . . .

that a film reel-like slipping of the windings is prevented.

The rod can be mounted in bores of lids put on the front side of the winding tubes. `~

Figure lb shows a part of a bag chain the bags thereof having lateral side folds.

Figure lc shows a part of a bag chain with side folds at the bottom and handle hole strengthenings at the top.

Figure 2 is a sectional view of a bag with a side fold at the bottom. .

Figure 3 is a longitudinal section of a supply roll formed by winding of a bag chain accordin~ to Figures la and 2 onto a winding tube the width of which corresponds to the bag -~
chain.

Figure 5 is a longitudinal section of a supply roll being formed, in which a bag web according to Figure lb is wound onto a correspondingly shortened winding tube.

Figure 6 is a schematical side view of an arrangement for the making of bag chains and supply rolls from these bag chains.

Flgure 7 is a longitudinal section of a supply roll being formed, onto which sacks with side folds and arranged in over-lapping or scale formation are wound together with holding straps.

Figure ~ is a sec~ional view of an arrangement for the making of sacks with side folds and arranged in overlapping or scale formatlon and for the winding of said side-fold sacks to form supply rolls.

Detailled Description of Preferred Embodiments An illustrated embodiment of the invention will now be described more in detail with reference to the drawings.

Figures la to ld show parts of bag chains to be wound to supply rolls. In the embodiment according to Figure la, the indi-vidual bags are provided with folds put into at the bottom and lateral weld seams, wherein the individual bags ar2 ~oined toge-ther via perforated lines arranged between the transversely ex-tending lateral weld seams of the bags.

In the embodiment according to Figure lb, the bag chain consists of a tube web having side folds, said web being provid-ed with transversely extending bottom weld seams in the distance of the individual bags and ad~acent transverse per$orated lines.

The bag chain according to Figure lc corresponds to the one ac-cording to Fi~ure la, apart from the fact that at the mouth edges of the bags handle hole stren~henings are provided.

In the bag chain according to Figure ld U-shaped handles welded thereon are provided in~tead of the handle hole strengthe-nings.

If bag chains according to Flgures la and 2, which con-sist of Jolned-together bags 1 with bottom folds, are wound onto a winding tube 2 to form a winding 3, this results in a supply roll of the kind known from Figure 3 with a ring bead 4 at the end.

In order to avoid said ring bead, as can be seen from Fi-gure 4, a winding tube 5 shortened ln its length is used so-that the ring bead can be pressed into the region between the one front side of the winding tube 5 and the supply roll 3 and also the section 6 at the bottom of the supply roll has no thicken-ing. Thus, the cylindrical supply roll as shown in Figure 4 can be produced.

In order to produce supply rolls of the kind as shown in Figure 4, an arrangement schematically shown in Figure 6 can be used. Said arrangement consist of a draw-off device for a web 7 of tubular foil. The drawn-of web 7 of tubular foil is then pro-vided with a side fold by a tool 8. The thus formed side fold tube then passes through a working station 9 in which for in-stance suspension hole~, weld and perforating seams are formed.
Subsequent ther~to the sack chain 10 formed by the tool 8 i~
wound onto a wlnding 3. Said arrangem~nt is of a basically known kind so that it need not to be discussed ln detail.

Figure 5 shows a sac~ chain 11 consisting of Joined-to-gether side-fold bags as known from Figure lb. Said sack chain 11 is wound to a roll 12, the winding tube 13 only being of such a length that the side fold sections 14 and 14' pro~rude lateral-ly so that said sections can make way in direction to the in-side. In order to obtain a perfect transport and above all a bearing of such a winding 12', front-side plates 15, 16 are pro-vided which form solid stack surfaces. Said plates 15, 16 are connected to each other via an axis 17 carried through washer plates 18, 19 in the tube 13. For the formation of such kind of a winding 12' also the arrangement as represented in Figure 6 can be used.

As an alternative to Flgure 5 showing a wound sack chain, also bags or sacks arranged in overlapping or slace formation can be wound to a winding 20. In this case holding straps 21, 22 are introduced during winding. The kind o production of such windings can be seen in Fi~ure 8 which ls not descr~bed in de-tall herein, slnce the schematically represented arrangement and the method carried out by means thereof has already been known from published patent publications.
