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.

An apparatus is disclosed for applying tags with attached elastic anchor bands onto the tops of objects such as bottles in a high speed packaging application. The apparatus includes an infeed assembly for feeding a web, a conveyor assembly that receives a web and conveys it along a path in an upstream direction, a rotating selector wheel, a placement assembly, a pair of rotating jaw assembles, a vacuum cup of the selector wheel, and stretched elastic bands over the tops of respective bottles being conveyed along a path below the placing assembly. The elastic bands then snap onto the tops of their respective bottles to secure the tags to the bottles.

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.

A sheet feeding device includes a sensor, a roller, and a support on which the sensor and the roller are disposed. The support supports the sensor and the roller so that the sensor and the roller contact a surface of the sheet roll. The sensor and the roller face toward an axial center of the sheet roll. The roller is spaced apart from the sensor in a circumferential direction of the sheet roll. The sensor has a detection accuracy capable of detecting a step at a leading end of the sheet roll.

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.

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.

Provided is an automatic coiled material switching device, which comprises a machine table (8), a left unwinding device (81), a right unwinding device (82) and a rotatory cutting device (83); wherein the machine table is provided with a left auxiliary roller (84), a right auxiliary roller (85) and a plurality of fixed rollers; the rotary cutting device comprises a bearing seat (1), a bearing (11) arranged on the bearing seat, a rotating main body (2) arranged on the bearing, a rotating mechanism for driving the rotating main body to rotate on the bearing seat, a turning mechanism for driving the bearing seat to turn around, and a driving mechanism; the rotating main body comprises an upper part (21) and a lower part (22); a gap (23) for allowing a material to pass through is formed between the upper part and the lower part; and the rotating body is provided with a pressing mechanism for compressing the material and a cutting mechanism for cutting the material. The automatic coiled material switching device implements the automatic switching of material belts of the left unwinding device and the right unwinding device by arranging the rotating main body, rotating mechanism, the turning mechanism, the driving mechanism, the pressing mechanism and the cutting mechanism.
