The invention concerns a splice arrangement with a first and second unwinding unit for unwinding a finite first or second material web and a connection apparatus. The connection apparatus comprises a guide, a first preparation apparatus and a second preparation apparatus. The connection apparatus also has a first and second connection apparatus for connecting the finite material webs to form an endless material web and a table unit, displaceable along the guide, for cooperation with the preparation apparatus and the connection apparatus. The splice arrangement further comprises an actuation apparatus for actuating the connection apparatus as well as the table unit.

A method for splicing a material associated with an absorbent article, including: transporting the material in a direction of transport with a material wound around an entrance roll and a moving roll of a dancer unit; splicing a subsequent material with a preceding material which is a material being transported, by bonding a leading end portion of the subsequent material with the preceding material; and cutting the preceding material so that the total length of a bonded portion and an stacking portion is larger than a path length of the material from a downstream end of a winding portion of the material that is wound around the entrance roll to an upstream end of another winding portion of the material that is wound around the moving roll positioned at a reference position.

A splicing apparatus for splicing together an engaged paper sheet with a replenishing paper sheet in a paperboard corner manufacturing system, the apparatus comprising: an engaged sheet holder for holding the engaged paper sheet; an engaged sheet cutter for cutting the engaged paper sheet to form a free engaged paper end; a replenishing sheet holder for holding the replenishing paper sheet; a replenishing sheet cutter for cutting the replenishing paper sheet to form a free replenishing paper end; a sheet end alignment device for positioning both free engaged and replenishing paper ends relative to each other and substantially aligned with each other; an adhesive tape applicator for applying an adhesive tape simultaneously to the aligned free engaged and replenishing paper ends such that the adhesive tape extends partially over the engaged and replenishing paper sheets to join the free replenishing paper end to the free engaged paper end.

Systems and methods for aligning preprinted images on a roll of substrate to the moving components of a web press are disclosed. A method in accordance with one embodiment includes determining the speed of the moving components of the press, determining the speed of the web of preprinted images and adjusting the speed of the web of preprinted image to match the speed of the web. In particular embodiments, a press which produces rolls of preprinted material can be modified to change the equivalent cutoff length of the press. In further embodiments, a method of pasting new rolls of material to expiring rolls of material is accomplished by modulating the drive speed of the new roll of material to match the expiring roll of material while at the same time aligning the images on the new roll with the expiring roll.

Splicing method and unit for a packaging machine, whereby a first film is spliced to a second film which is a spare film. The splicing is performed by means of an adhesive element with two opposing adhesive surfaces, one for each film, and a longitudinal adhering element. First an adhesive surface is adhered to the adhering element and said adhering element moves so that the other adhesive surface comes into contact with the second film and adheres to it. Then the adhering element is separated from said second film, the adhesive element being adhered to said second film, and the first film is caused to come into contact with said adhesive element already adhered to the second film.

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 secondary battery electrode film and separator supply device configured to: replace a bobbin when an electrode separator is used up by automatically extracting an empty bobbin from a spool, mounting the empty bobbin on a side of a bobbin mount of a bobbin changer, changing the position of a new bobbin mounted on another side by rotating the bobbin mount 180 degrees, and then moving and mounting the new bobbin on the spool; automatically extracting an end of a wound electrode separator through vacuum suction and connecting the end to another electrode separator; and feed a replacing material roll to a moving spool, cut a finishing tap at an end of a material by a predetermined length, and then automatically connect a new separator end of the replacing material roll and an in-use separator end through taping.

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.
