Method and Device for Successively Winding a Film Web, and Film Roll
20210403267 · 2021-12-30 ·

The invention relates to a method for successively winding a film web onto a plurality of spools, wherein the film web is wound to form a first spool, and a tube and/or winding shaft for forming a subsequent second spool and the film web are moved closer to one another and/or are brought into contact with one another upstream of the first spool. The film web is cut, and thus an end of the film web is produced, with end is wound onto the first spool, and a new start of the file web is produced, which is wound onto the second tube. In order to cut the film web, the film web is cut partially in the transverse direction, at least one cut edge and at least one uncut region remaining in the transverse direction, the uncut region being subsequently torn off or cut off.

FEEDING UNIT FOR A TISSUE CONVERTING MACHINE FOR CONVERTING A WEB OF TWO-LAYER TISSUE
20210371226 · 2021-12-02 ·

The feeding unit (10) comprises: support means (12) for rotatably supporting a first reel (R1) of two-layer tissue web and a second reel (R2) of two-layer tissue web about respective axes of rotation (x1, x2); cutting means (32, 42) for cutting the two layers (L1_1, L2_1) of the tissue web (W1) of the reel (R1) in use, the cutting means (32, 42) being configured to cut the two layers (L1_1, L2_1) of the tissue web (W1) along two cut lines spaced apart from each other in the longitudinal direction of the web (W1); joining means (44_1, 44_2) for joining each of the two layers (L1_2, L2_2) of the tissue web (W2) of the other reel (R2) of said first and second reels (R1, R2), and precisely of the new reel, to a respective layer (L1_1, L2_1) of the tissue web (W1) of the reel (R1) in use; and tissue web accumulation means (30) for accumulating a given amount of web (W1) downstream of the cutting means (32, 42) and the joining means (44_1, 44_2) so as to ensure the feeding of the machine with the tissue web (W1) while the portion of tissue web (W1) on which the cutting means (32, 42) and the joining means (44_1, 44_2) act is kept temporarily still to allow the cutting of the two layers (L1_1, L2_1) of the tissue web (W1) in use and the joining of the latter with the two layers (L2_2, L2_2) of the new tissue web (W2).

METHOD AND APPARATUS FOR SEPARATING AND SPOOLING A PAPER WEB
20220204296 · 2022-06-30 ·

An apparatus for dispensing an adhesive with paper covers to be used in a paper web turn-up operation. The resulting adhesive and paper cover construct is used in effecting the attachment of a paper web to an approaching spool. In some examples, the paper cover of the deposited adhesive may be affixed on two sides surrounding the deposited adhesive, in other examples a single attachment may be used. In some examples, the paper cover may be perforated to facilitate rupture of the paper and flow of adhesive. In some examples, perforations may enable the movement of adhesive through the paper.

Device for winding and changing the reels of web material as well as a dedicated process

A device for winding and changing reels of web material includes two independently operable central drives for shifting winding shafts, a drivable winding shaft guide, a contact roller unit and slitting units. Both right-hand winding and left-hand winding are realized, whereby the device is without a prewinding station. For a winding shaft change, the drivable winding shaft guide is driven from the winding position into the parking position and is disconnected. Subsequently, the second central drive is connected to the winding shaft guide and is driven from its parking position into the winding position where the second central drive is connected with a new winding shaft. The contact roller unit is driven against the winding shaft and the web material is cut through by a slitting device and then wound to a new reel.
