The invention relates to a method for introducing a material web into a corrugating device having a corrugating roller for generating from the material web a corrugated web. The method comprises the step of attaching at least one double-sided adhesive tape piece which has a first adhesive face and a second adhesive face that is opposite the first adhesive face to the material web by means of the first adhesive face upstream of the corrugating device of the material web, and guiding the material web through the corrugating device in such a manner that the second adhesive face adheres to the rotating corrugating roller while entraining the material web for introducing the material web.

The present invention concerns a method for joining the ply of a reel of paper in depletion with the initial flap of a new reel, as well as an apparatus adapted for carrying out such a method. Thanks to the method according to the present invention, and to the apparatus suitable for carrying it out, the joining of the reels takes place without using gluing means, like for example the double-sided tape used in known methods, avoiding the relative drawbacks, the adhesion between the plies of the reels to be joined taking place by electrostatic attraction.

The disclosed supply roll (5) comprises a roll core (6); flat material and/or strip material (8) being carried on the roll core (6) in a multitude of windings; and at least one functional marker (2). The at least one functional marker (2) is placed in a specified relative position at an externally arranged free end section (7) of the flat material and/or strip material (8) such that information about the relative position of the free end section (7) is optically identifiable by way of the at least one functional marker (2).

A coil replacing device. When a first unreeling assembly at an unreeling station finishes unreeling, a fixing suction member can be driven by a first driver abutting against a first suction member clamping a working material tape, a first cutting assembly cuts off the working material tape, and the cut working material tape is sucked by the fixing suction member. Then, a vertical plate slides to make a second unreeling assembly enter the unreeling station, a material tape sucked by a second suction member will also enter the unreeling station as a spare material tape, and the first unreeling assembly will be removed from the unreeling station. The fixing suction member is driven by the first driver to abut against the second suction member, so as to realize coil replacing, and the first unreeling assembly can be loaded with a new material tape to serve as a spare material tape.

Adhesive tape for the on-the-fly roll changeover of flat web material wound up into rolls, comprising a carrier layer having a first surface and a second surface, a first layer of adhesive on the side of the first surface over at least part of the area, and a second layer of adhesive on one or more areas of the second surface, wherein the adhesive tape has regions suitable for areal splitting, at least those areal regions of the second surface on which the second layer of adhesive is provided being surface coated, the forces of adhesion of the lower layer of adhesive to the surface coating being greater than the forces of adhesion of the surface coating to the carrier layer, and/or the forces of adhesion of the lower layer of adhesive to the surface coating being greater than the forces of cohesion within the surface coating.

A method for cutting and connecting two bands end to end and which are at a stop, namely a first band ensuring the feed, and a second replacement band, in an unrolling machine including a cutting and connecting device including two connection assemblies arranged symmetrically with respect to a cutting and connection plane is provided. Utilizing the unrolling machine the method includes preparation of the second band, then immobilization of the bands in the plane, of simultaneous and transverse cutting of the latter, of disengagement of the cut portions not to be connected, and of end-to-end connecting of the cut portions thereof to be connected. A cutting and connecting device and a machine enabling the implementation of the method is also provided.

Devices, methods, and systems for splicing a trailing edge of an outgoing roll with a leading edge of a replacement roll with a lapless butt splice on-the-fly during converting and printing production. A first strip of adhesive tape may be placed partially under the leading edge, such that a portion of the adhesive tape remains exposed beyond the leading edge. The replacement roll may be accelerated to match the speed of the outgoing web's movement, a trailing edge of the outgoing web may be cut free from the outgoing roll, and the trailing edge of the outgoing roll may be positioned over the exposed portion of the adhesive tape. A second strip of adhesive tape may be applied over the leading edge and trailing edge using a splicer roller timed to apply the tape when the edges pass proximate to the splicer roller.

An apparatus and method for assembling, dispensing and using a laminated paper web transfer tape, an embodiment of the apparatus having a pair of transfer tape spools enclosed within a cartridge dispenser, one transfer tape spool containing a first tape component of the laminated transfer tape and the other transfer tape spool containing a second tape component of the laminated transfer tape, the first tape component being the combination of a substrate having adhesive on both sides and a release liner, the second tape component being a cover flap member having a release coating over at least a majority of one side. The components are unwound from the spools and pressed together such that they become joined along a longitudinal edge strip, then dispensed from the housing. The cover flap member covers one of the adhesive sides of the transfer tape substrate until the moment just prior to transfer of a continuous paper web from a full web spool to an empty web spool, the cover flap member being opened to expose the adhesive by air pressure or resistance. The cartridge dispenser is removed retained within a dispenser frame.

A method and device for carrying out a reel splice to avoid the fluttering of tails makes it possible to allow the tail to also adhere across its entire length, in particular on a web with high mechanical strength. When using a fluid-repelling substrate, an adhesive-free liquid is applied to a new roll and/or to at least a portion of the side of the tail facing the web. The method and device can be used in reel splicers which process fluid-repellent substrates, such as for example plastic films, metal films or laminated laminates, so that a sticking out or fluttering of the tail is avoided.
