^ Method and device for producing winding δ bundles made from slit tape and wrapped band

! Ο The invention relates to a method for producing Wraps made of slit strip, in which the metal strip is drawn off a reel, in the longitudinal direction in a plurality of narrow ribbons is split and the so generated

Slit strips are rolled up parallel to each other to form bundles

be wrapped. The invention also relates to a Device for performing this method and also a device according to this method or on this he device

made of slit tape. 20th

Wrap bundles made of slit tape have so far been made in such a way that that one pulls a metal strip from a reel or a coil and then in the longitudinal direction in narrow

² ^ splits strips, which are wound together parallel to one another on a driven mandrel that carries a number of discs, which serve as a spacer element between the individual split strips, so that these are wound into individual coils. After completion of the winding process, these bundles must be removed individually from the mandrel, tied together on a special device with sheet metal tape and finally stacked for storage.

In particular with very narrow slit strips in the width range from 5 to 15 mm, the most varied results Problems. Due to the laws of physics, the ring diameter of the coil is limited, and indeed may the bundle should not be heavier than 3 kg per mm of slit strip width. By winding with attached to the mandrel Spacers and the necessary tying of the

individual winding bundles result in high costs due to 10

the necessary manual set-up times. During handling, failures due to the accumulation of scrap cannot be avoided, i.e. in particular from the center of the individual winding bundles, slit tape runs out before the bundle is tied together is. This leaked slit tape can generally only be used as scrap and has to be cut off will. When handling the wound bundles, industrial accidents for workers cannot be completely avoided.

Furthermore, there are internal storage and transport problems. In addition, the slit strips can be deformed in the shape of a saber. Eventually arise from time to time Damage to the cut edges of the slit strips during transport and storage movement of the finished wound bundles.

Attempts have been made to overcome these problems by removing the metal strip running off the reel or coil not completely, but only partially divides,

so that the adjacent slit strips still remain connected to one another at individual points. These connection points are chosen so that they separate without difficulty when unwinding the individual slit strips

permit. In this way you can with wraps

Produce larger ring diameters and also reduce storage and transport problems, but the result is Disadvantage that the cut edges of the slit strips are not

are uniform because the break points where the 5

Slit strips still from each other when unwinding from the wrapping collar be separated, leave behind a certain clarity. Therefore, such slit strips often meet

not the demands of customers. 10

The invention is based on the object, in a particularly economical manner, wound bundles made of slit tape and in particular to produce a narrow slit band between a band width of 5 to 15 mm, which also varies according to their Completion can be handled and unwound in an advantageous and operationally reliable manner, and the slit strip is flawless Quality included.

According to the invention, this object is achieved by

that when winding the completely separate slit strips between the individual layers of the same a sheet-like or foil-like intermediate layer is inserted

puts and is wrapped with it, which the individual slit-band bundles wound next to each other connects. Preferably, the individual slit strips are spaced apart from one another with the 30th

Interlayer wound into a composite roll.

According to the invention, a composite winding is thus produced, which consists of a plurality of individual slit band bundles, which are spread over the entire by means of a

Width of the composite roll extending insert made of paper or plastic film interconnected and thereby be held together. It is only necessary to secure the individual slit band bundles against unwanted unwinding

required to attach the outermost end of each slit tape to the winding collar, for example by means of a Adhesive tape to stick. To unwind the individual slit-strip bundles or slit strips, it is only necessary to

* 0 required, the outer end of the corresponding slit strip to solve and then unwind this covenant. The remaining slit band bundles of the composite roll remain wound up, without any special measures for the special security of the same being necessary. Also, no special edge protection of the individual slit band bundles is necessary because the wrapped one Intermediate layer at the front ends far enough over the

2Q bunMckel can withstand damage to the edges to avoid the outer split tape bundles, and because the individual slit-strip bundles of the composite wrap from the Liner must be kept at a sufficient distance from each other to prevent damage from mutual Avoid contact between neighboring slit strips.

The invention makes it possible to reduce the bundle weight and thus the ring diameter of the individual bundles.

'

bigger. There are bundle weights of up to 10 kg per mm Gap width possible. So one has according to the invention For example, bundle weights of 1000 kg are achieved. The composite roll can, for example, contain 20 slit tape bundles have, with an outer diameter of up to 1300 mm and inner diameters of 300, 400 or 500 mm.

oouuouo

The greatest width of the composite roll can be up to 1500 mm or more, which not least depends on the length of the dome available for the winding process.

The composite roll to be produced according to the invention can be removed from the winding mandrel as a compact unit and be transported and stored in the form of this unit. The entire composite roll attached to a reel and rotated in the unwinding direction, although not all slit strips be unwound at the same time. Larger sewing densities have to be moved here, but the unreeling is necessary overall more economical because the composite winding only has to be slipped onto the reel once and it is then not necessary to remove multiple tapes from the individual split tape bundles before using them can be unwound. Rather, it is sufficient to secure the outer end of the slit band in question y before unwinding.

Preferably the one inserted during winding is used

Intermediate layer when unwinding or unwinding the individual _{slit tape} bundles divided into layers between the adjacent ΟΛ bundles, so that the intermediate layer only protrudes a short distance over the ends of the remaining composite winding, which is sufficient to ensure the desired edge protection. The severed strip

the intermediate layer is expediently 35 during the unwinding process

reeled up and can be thrown away ^

* To solve the problem, a device is also proposed which has a device for feeding in a sheet-like insert or intermediate layer

g between the individual layers or turns of the slit strips when winding the same and a cutting device for separating the insert layer by layer during unwinding the individual slit band bundles. if

Another reel for unwinding the split strip bundles 10

as used to make the composite roll, the cutter is on that used to unwind To attach the reel.

The cutting device is preferably a continuously radially adjustable knife, which is in a stationary Position on the insert or intermediate layer of the composite roll in the space between two adjacent ones Acts on slit strips. This is a particularly simple and practical cutting device.

Finally, the object of the invention with a Winding collar detached from slit band, which has several slit band bundles spaced apart from one another, between the layers or turns of which each form a continuous sheet-like sheet that holds the individual slit band bundles together

Insert made of material that can be dismantled, such as paper or art-30

fabric film is located, which is appropriate over the front ends of the winding collar protrudes a short distance to the longitudinal edges of the also on the front sides of the winding collar

To protect slit strips against damage of any kind. 35

OClUUOUO

The distance between the adjacent slit strips is preferably approximately 2 mm. This distance is enough for one effective edge protection of the slit strips.

Since no packing tape is required to hold the split band rings or collars together, no closure sleeves can be used either from packing tapes cause pressure points on the side edges of the slit tapes. A saber formation of the individual slit strips are largely avoided because of the space between the individual turns Inlay made of paper or plastic film prevents burrs of the split strips from twisting twisting can add, but rather be compensated. With the invention, it is possible even with bandwidths below 10 mm can be used to produce winding diameters of practically any size, with bundles that are three times as large without any problems

2Q achievable or belt lengths three times as long as before possible to be rolled up into a bundle. A laborious threading of individual slit strips by hand and the insertion of cutting discs between the individual

Tape strip is not necessary because without cutting discs 25

or partitions are worked and accordingly all slit strips running parallel to one another in threaded into the reel in a single operation can be, no matter how large the number of

slit strips to be wound up at the same time.

During transport, the one produced according to the invention is Composite roll, which, like a kind of magazine, contains a larger number of split band bundles, the conventional one

Highly superior to individually wound slit band coils, as the individual slit bands go through with the composite winding the insert made of paper or plastic film are fixed and thus a safe transport unit

form. Storage and stacking of such

Unity are hassle-free. The processor can bring up to 60 units to his decoiler with a single crane lift. Needlework times ¹ ^ are largely avoided as a composite winding accommodate up to three times the length of tape and juxtaposed to can contain 20 to slit strip-league.

The processor can interrupt the separation, i.e. the unwinding of one of the slit strip bundles at any time, and even in the middle of the unwinding process of a split strip bundle, so that the rest can be done again without any further packing work

2Q can be brought back to the warehouse.

The deposits provided according to the invention have the Another advantage that the surface of the slit strips

largely against mechanical loading due to the insert

Damage is protected, which is particularly important with sensitive materials.

Due to the introduction of the deposit, the currently 30

saved costs for mechanical strapping when packing the individual slit band bundles will. Handling the composite lap is also much less prone to accidents than handling individual ones narrow split tape bundle.

JOUUÜUJ

To further explain the invention, the drawing shows an embodiment of an uncoiler device with which a gap according to the invention

g tape composite winding can be unwound, namely the individual split tape bundles each for itself, namely shows

Fig. 2 is an end view of the same.

The decoiler has one on a base plate 1 fixed stand 2 on which a mandrel 3 is rotatably mounted. Furthermore, on the base plate 1 is a Winder 4 arranged with a rotatably mounted shaft 5, with the help of which one of the insert of the Winding collar, separated tape 6 made of paper, plastic film or the like. Can be wound up.

A composite roll 7, which is connected to the mandrel 3 in a rotationally fixed manner, is pushed onto the mandrel 3 of the decoiler. The composite roll 7 consists of a number of slit-band coils 8, which have an insert 9 made of paper, plastic

_or . Fabric-foil or the like. Are interconnected. This insert 9 is inserted between the individual turns of the slit strip and extends over the entire length of the composite roll 7. Preferably, the insert 9 protrudes somewhat over the front ends of the composite roll 7

also the side edges on the front sides

to protect the slit strips 10 against damage. These protruding ends of the insert 9 are shown in FIG 2 not shown.

As Figure 2 shows, is located between the Insert 9 held together adjacent slit band collars 8 each a certain distance, for example Can be 2 mm. This prevents adjacent slit strips from touching one another and one another can damage.

A cutting knife 11 is assigned to the mandrel 3 and is mounted pivotably about an axis 12. This cutting knife 11 cuts the insert 9 between it when the foremost slit band bundle 8a is unwound and the next following split band bundle 8, so that a strip 6 of the insert 9 runs off and from the winding device 4 can be wound up. The Trehnmesser 11 is mounted pivotably about the axis 12, so it can follow the decreasing outer diameter of the foremost slit band 8 and separate the insert 9, until the slit strip 10 has completely expired from the foremost slit strip bundle 8a.

The slit strip 10 runs from the foremost slit strip bundle 8a 30

under a loop regulator 13 through to a not represented consumer.

So that the foremost slit band bundle 8a is in the correct position in relation to the cutting knife 11,
