Preventing the fluttering of the tail in film printing
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.
ADHESIVE PIECE
The invention relates to an adhesive piece for the adhesive connection of material webs. The adhesive piece comprises an adhesive compound carrier which bears adhesive compound on two opposite sides, and at least one release liner which originally covers, at least in certain regions, the adhesive compound carrier and also the adhesive compound present there, protrudes at least in certain regions beyond the adhesive compound carrier, and is removable by a release liner removal apparatus.
RELEASE LINER REMOVAL APPARATUS
The invention relates to a release liner removal apparatus, comprising at least one release liner removal device for removing at least one release liner from at least one adhesive piece arranged on a material web, at least one support body which supports the at least one release liner removal device, and at least one guide body which is arranged adjacent to the at least one release liner removal device at least during the removal of the at least one release liner and which serves for guiding the material web.
MATERIAL WEB DRAWING-IN APPARATUS
The invention relates to a material web drawing-in apparatus for drawing in a material web. The material web drawing-in apparatus comprises at least one material web holding device for holding the material web to be drawn in, and at least one guide for guiding the at least one material web holding device from a material web drawing-in point to a material web transfer point, and also at least one drawing-in drive which is in connection with the at least one material web holding device and which serves for displacing the at least one material web holding device along the at least one guide upon drawing in the material web to be drawn in in the direction of the material web transfer point.
MATERIAL ROLL PREPARATION ARRANGEMENT
The invention relates to a material roll preparation arrangement. The material roll preparation arrangement comprises a receiving apparatus for receiving a material roll to be prepared with a wound material web, and at least one material roll preparation apparatus which is assigned to the receiving apparatus for the preparation of the material roll which is received in the receiving apparatus for further processing, in particular in a corrugator plant.
MATERIAL WEB DRAWING-IN APPARATUS
The invention relates to a plant having at least one material roll preparation arrangement for bringing a material roll carrying a material web to be drawn in into a defined initial situation, and having at least one material web working/processing arrangement, in particular material web dispensing arrangement, in particular material web unrolling arrangement, in particular material web splicing arrangement, which material web working/processing arrangement is capable, owing to the defined initial situation of the material roll, of receiving the material roll in automated fashion and preferably receiving the material web in automated fashion and/or preparing the material web in automated fashion.
Method for joining two webs together with an adhesive tape
The invention relates to an adhesive tape with a carrier composed of a film, there being applied on one side of the carrier an adhesive based on natural rubber or synthetic rubber, where the film is a biaxially oriented film made of polypropylene, polyethylene or polyester such as PET, and on the side of the carrier not coated with adhesive there is a release layer, based in particular on carbamate.
Splicer assembly
The invention relates to a splicer assembly for splicing material webs. The splicer assembly comprises a first dispensing device for dispensing a finite first material web, a second dispensing device for dispensing a finite second material web, a connecting device for connecting the finite first material web and the finite second material web so as to form an endless material web, and a material web threading assistance assembly for assisted threading of the finite first material web or of the finite second material web into the splicer assembly in a threading procedure. The material web threading assistance device comprises at least one conveying installation for conveying the finite material web to be threaded in a threading direction in the threading procedure, and a conveying installation drive installation for driving the at least one conveying installation in the threading procedure.
AUTOMATIC LAPLESS BUTT MATERIAL SPLICE
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.
Device for storing and removing cardboard for a bridge in a corrugated cardboard production line
A device for cardboard storage and removal for a bridge in a corrugated cardboard production line includes a bridge over which a conveyor system for conveying the single-sided laminated corrugated cardboard web is arranged. The exit end of the conveyor system for conveying the single-sided laminated corrugated cardboard web is provided with a clamping and cutting unit and a movable cardboard storage carriage unit is provided under the conveyor system for conveying the single-sided laminated corrugated cardboard web, under which conveyor system a conveyor belt system is provided in the bridge, and in the bridge an opening is provided, under which a waste cardboard collecting carriage is provided. The movable cardboard storage carriage unit stores the cardboard by means of cardboard storage rolls, which retain the single-sided laminated corrugated cardboard web flat on the bridge. In the event that a splicing defect is detected, the defective piece is cut out by the clamping and cutting unit and ejected by the conveyor belt system to the waste cardboard collecting carriage through the opening. Hence, it follows that productivity is improved.
