A joining apparatus for supporting strips of adhesive labels comprises two modules each of which in turn comprises a conveying element of the respective supporting strip; a cutting element configured to cut a respective supporting strip; a joining element that can be configured in a first operating position, in which it keeps in position a respective supporting strip and/or a fixing element, and in a second operating position in which it abuts against the joining element of the other module so as to join the supporting strips; a locking element that can be configured between an active position and a passive position. In particular, at least one joining element can be removed from the respective module to allow the introduction of the fixing element even when the two modules are in the neared configuration to one another. The subject matter of the present patent application is also a joining process for supporting strips of adhesive labels.

A splicing apparatus for splicing two material webs for the production of power storage devices provided with a splicing assembly comprising: at least two feeding units, each configured to feed a respective material web; and a splicing unit configured to splice the two webs by means of an adhesive tape applied on one of the two webs. The splicing unit comprises a movable deflecting element configured to move along a splicing surface defined by the two material webs to be spliced and is movable between a disengagement position, in which the deflecting element is spaced apart from the first material web, and a transfer position, in which the deflecting element at least partially engages the first material web so as to at least partially stretch it when the web is released onto the second feeding unit.

An electrode connecting device for connecting an end of a preceding sheet to an end of a succeeding sheet includes: an arrangement member provided with an arrangement part on which the end of the preceding sheet is located adjacent to or overlapping with the end of the succeeding sheet; and a guide member having a guide bar which is provided movable between a support position to support a side portion of the preceding sheet and a side portion of the succeeding sheet during connecting of the end of the preceding sheet to the end of the succeeding sheet and a retreat position not to interfere with movements of the preceding sheet and the succeeding sheet.

A roll exchange chamber for exchanging a substrate roll is described. The roll exchange chamber includes a rotatable base construction being rotatable around a central axis. The base construction comprises a first roll holder for holding a first substrate roll, a second roll holder for holding a second substrate roll, and a wall for providing a first compartment and a second compartment in the roll exchange chamber. The wall is arranged between the first roll holder and the second roll holder. Further, a roll-to-roll processing system with a roll exchange chamber as well as a method of continuously providing a flexible substrate in a roll-to-roll processing system are described.

An apparatus and method for automatic splicing of rolls of sleeve material used in various packaging applications. The disclosed system will automatically splice the leading end of a new roll onto the trailing end of the old roll in an overlapped configuration. The apparatus performs an automatic cut and splice operation resulting in a splice of the two film rolls with tape applied to both sides of the splice joint where the new roll overlaps the cut end of the prior roll.

A method for feeding a production line of absorbent sanitary articles with a layer of a virgin multilayer tape including providing a head free end of the virgin multilayer tape partially unwound from a respective virgin spool; providing a tail free end of a multilayer tape in use; applying a first connecting element on a first layer of the virgin multilayer tape and on a first layer of the multilayer tape in use at the head free end and tail free end; applying a second connecting element on a second layer of the virgin multilayer tape and on a second layer of the multilayer tape in use at the head free end and tail free end; pulling the first layer of the virgin multilayer tape in a first direction; pulling the second layer of the virgin multilayer tape in a second direction.

The present application relates to a roll replacing device and a tab welding apparatus. The roll replacing device includes an unwinding mechanism, a first fixing mechanism, a second fixing mechanism, a cutting mechanism, and a strip connection mechanism; wherein the first fixing mechanism is capable of following a sliding bracket to move along a first direction until a spare material strip fixed by the first fixing mechanism and a working material strip fixed by the second fixing mechanism are aligned at a strip connection station, and allows the strip connection mechanism to connect the working material strip and the spare material strip which are aligned at the strip connection station.

An apparatus (100) for splicing a patterned web (108) is provided. The apparatus includes first and second unwind spindles (110, 114) engaging a new roll (112) of patterned web (108) and expiring roll (116) of patterned web, respectively, a first web indexing mechanism (104) capable of linearly translating the patterned web from the new roll (112) along its travel direction; a first clamp surface (129) that extends across the patterned web from the new roll; a second clamp surface (131) that extends across the patterned web from the expiring roll (116); and a cutting mechanism (132, 132) for severing the patterned web from the expiring roll (116). The apparatus further includes a second web indexing mechanism capable of linearly translating the patterned web from the expiring roll along its travel direction, wherein the first and second web indexing mechanisms are independently operable to align registration features of the patterned web on the new roll and expiring roll with each other. The first and second clamp surfaces can be brought together to create a registered splice of the patterned web between the new and expiring rolls.

The present invention relates to a method for splicing an upstream section and a downstream section of a multi-layered laminated sheet material wherein each section of the material comprises at least three layers each having first and second surfaces and wherein the at least three layers comprise first and second outer layers and at least one inner layer located between the first and second outer layers, comprising the steps of a) splicing together the upstream and downstream sections of both the first and second outer layers with a splicing material; b) removing the first outer layer from the multi-layered laminated sheet material to expose a surface of an inner layer; c) splicing the upstream and downstream sections of the exposed inner layer with a splicing material; and d) applying a replacement first outer layer to the exposed surface of the inner layer. A spliced multi-layered laminated sheet material produced according to the method is also provided. Also provided is an apparatus for splicing two sections of a multi-layered laminated sheet material wherein each section of the material comprises at least three layers each having first and second surfaces and wherein the at least three layers comprise two outer layers and at least one inner layer located between the two outer layers, the apparatus comprising: a first splicer configured to apply a splicing material to the two outer layers of the multi-layered laminated sheet material, a delaminator configured to remove a first outer layer, a second splicer located downstream of the delaminator configured to apply a splicing material to the exposed inner layer and an applicator located downstream of the second splicer configured to reapply an outer layer to the exposed inner layer.
