A method and apparatus for automatically splicing two continuous three-layer tapes, wherein a longitudinally movable continuous wound tape is transversely cut so as to form individual wound pads which are applied in longitudinally spaced positions on adhesive surfaces of continuous carrier foils, and wherein a splicing element is cut from the continuous wound tape and is applied on tail and head portions of two continuous carrier foils.

A sheet delivery system includes: an end section detector which detects a position of an end section of a sheet; an end section conveying apparatus which holds the end section of the sheet and which conveys the end section of the sheet to a joining unit; a roll driving motor which rotationally drives a standby-side original material roll around a central axis thereof; and a suction roller which is capable of coming into rolling contact with an outer peripheral surface of the standby-side original material roll, and which includes an outer peripheral surface capable of suctioning the end section of the sheet in order to separate the end section of the sheet from the standby-side original material roll. The end section detector is attached at a position which enables detection of the end section of the sheet separated from the standby-side original material roll by the suction roller.

An automatic replacement device of a secondary battery material including reel support parts to support a supply reel; a material support part spaced apart from the reel support part; clamping parts, each including a clamping roller to come into contact with the material when replacing the supply reel, a vacuum suction part to suction the material by vacuum, a clamping frame to rotatably support the clamping roller and the vacuum suction part, and a cutter to cut the material when coming into contact with the material; first drive parts to move the clamping roller toward/away from the material; and second drive parts to move the cutter toward/away from the material, wherein the automatic replacement device cuts the material as the material is suctioned to the vacuum suction part after being adhered to a material wound around a replacement supply reel when the supply reel is replaced.

A sheet delivery system includes: an end section detector which detects a position of an end section of a sheet; an operation robot which holds the end section of the sheet and which conveys the end section of the sheet to a joining unit; a roll driving motor which rotationally drives the standby-side original material roll around a central axis thereof; and a suction roller which is capable of coming into rolling contact with an outer peripheral surface of the standby-side original material roll, and which includes an outer peripheral surface capable of suctioning the end section of the sheet in order to separate the end section of the sheet from the standby-side original material roll. The end section detector is attached at a position which enables detection of the end section of the sheet separated from the standby-side original material roll by the suction roller.

The invention comprises a method and a device for changing removable carrier units (8a, 8b) with flat packaging material (10) wound on supply rolls (9), in particular, packaging film (11) within a packaging machine (3), which is equipped with devices for at least partially wrapping piece goods, containers, article groups, etc., with flat packaging material (10). With the method removable carrier units (8a, 8b) with new supply rolls (9) are fed in a series one after the other to a work area (AB) of a handling device (5), the work area (AB) of which extends into at least one position of the operating position of the removable carrier unit (8a, 8b) arranged in the packaging machine (3), which is equipped with a supply roll (9), so that it replaces removable carrier units (8a, 8b) located in the packaging machine (3) and used up supply rolls (9) with new removable carrier units (8a, 8b) with in each case a new supply roll (9). Here respective removable carrier units (8a, 8b) are inserted alternately in at least two different installation positions of the packaging machine (3) and its flat packaging material (10) is connected with the packaging material still located in the packaging machine (3).

Described is a web feeding system for feeding a web of labelling material to a labelling module that includes a splicing device. The feeding system includes a positioning device for automatically positioning the web leading portion of the web in a splicing position with respect to the splicing device.
