There is described a web alignment device for aligning a web comprising an engagement surface for supporting the web, a clamp assembly for clamping the web on at least a clamp portion of the engagement surface, an alignment control assembly for controlling a correct alignment of the web. The alignment control assembly comprises a control unit for generating a trigger signal if the web is correctly aligned, a first sensor device for detecting and/or determining a desired position of a first section of the web and to send at least a first signal to the control unit if the first section is positioned in the desired position, and a second sensor device for detecting and/or determining a desired position of a second section of the web and to send a second signal to the control unit if the second section is positioned in the desired position.

The present disclosure relates to a method for splicing a web of packaging material, comprising: guiding the web of packaging material through a splicing device comprising one or more imaging devices, a slitter, and a sealing unit; acquiring a first set of images of one or more areas of the packaging material, storing the acquired first set of images, slitting the web of packaging material in one or more locations to form a tail end and a head end of a web of packaging material, aligning the head end and the tail end and superimpose one on the other in preparation for forming a splice, utilizing the imaging devices and the stored acquired first set of images to fine tune the alignment of the head end and the tail end, sealing the splice.

Systems and methods for connecting the films of a first roll and a second roll in a packaging machine. The system includes a cutting device to cut the film of a first roll at a cutting position upstream side of a holding position with respect to a feeding direction toward a former while the film is held by a holding device. The system also includes a robot to move the second roll to a connecting position where a leading end of second roll film overlaps with a film terminal end of the first roll film. The system further includes a connecting device to connect the film leading end of the second roll film to the film terminal end of the first roll film. The robot to move the second roll from the connecting position to a set position after connecting the films, so that the second roll film is tensioned.

The invention relates to an adhesive dispenser comprising: a platform; an unwinder reel pivotally mounted on the platform and designed to carry a roll of adhesive; a separator member (9) for separating adhesive from the roll of adhesive, the separator member being arranged on the platform; the adhesive dispenser comprising at least one embossing roller (18) arranged on the platform between the unwinder reel and the separator member so that, in operation, it embosses the adhesive tape (3) being unwound from the roll of adhesive before it reaches the separator member.

The invention also relates to a device for connecting together two flattened tubular sheaths including such an adhesive dispenser.

A transport device includes a feeding portion feeding a printing medium, a winding portion winding the printing medium fed from the feeding portion, and a coupling portion coupling the printing medium on a feeding side extending from the feeding portion and the printing medium on a winding side extending from the feeding portion between the feeding portion and the winding portion, wherein the coupling portion includes a cutting table supporting the printing medium, a first fixing roll temporarily fixing the printing medium on the feeding side to the cutting table, and a second fixing roll temporarily fixing the printing medium on the winding side to the cutting table, and the first fixing roll and the second fixing roll temporarily fix each printing medium in a state in which a boundary between the printing medium on the feeding side and the printing medium on the winding side is exposed upward.

Disclosed in the present application are an automatic roll replacing device, and winding equipment. The automatic roll replacing device includes: a mounting frame; an unwinding mechanism, including an unwinding shaft rotatably connected to the mounting frame around its own axis; a spare material mechanism, including a spare material shaft having a contact end and a material pushing member providing an axial pushing force for a spare material roll on the spare material shaft, the spare material shaft being rotatably connected to the mounting frame around the rotation axis, and the material pushing member being controlled to push the spare material roll on the spare material shaft to transfer to the unwinding shaft; and a strip connection mechanism, provided on the mounting frame, and used for cutting off a work material strip unwound from the unwinding shaft and connecting the cut-off work material strip to the spare material roll.
