A device for slitting a tubular workpiece into strips includes radially disposed cutting members. The device may include a tapered infeed mandrel for maintaining tension on the tubular workpiece being slit and optionally an exit mandrel. In embodiments, the position of the radially disposed cutting members may be adjustable.

A sheet material conveying device unwinds from a roll body a sheet-shaped member constituting a membrane electrode assembly and conveys the sheet-shaped member. The sheet material conveying device is equipped with a suction member that moves the sheet-shaped member, and a negative pressure supply unit that supplies a negative pressure to the suction member. The suction member is constituted by a porous body capable of sucking under the negative pressure one surface of the sheet material having been unwound from the roll body and is movable in a conveying direction.

Provided is an adhesive film production apparatus for producing an adhesive film having an adhesive layer on a base material layer, the adhesive layer having an elastic modulus at 230 C. of 1 MPa or greater and having a glass transition temperature higher than normal temperature, the adhesive film production apparatus including a feeding roller; a cutting part; and a plurality of winding cores, wherein the raw film of the adhesive film is wound on the feeding roller such that the adhesive layer faces outward, and wherein in the conveyance path of the adhesive film traveling from the cutting part toward the winding core, the number of times of the adhesive layer of the adhesive film bending in a convex manner is set to be equal to or more than the number of times of the adhesive layer bending in a concave manner.

A processing apparatus comprises: a conveyance part for conveying a sheet; a processing part including a processing member that is installed in a manner of being movable in an intersecting direction of intersecting with a conveyance direction of the conveyance part and that performs predetermined processing at a predetermined position of the sheet under conveyance; a stacker part for accumulating processing articles obtained by the processing of the processing part; and a control part for controlling the stacker part such as to sort a predetermined amount of precedently ejected ones of the processing articles from the subsequent ones of the processing articles among the processing articles ejected to the stacker part by the conveyance part.

Provided is a printing device including a printing mechanism that performs printing on a long medium and a cutting mechanism that cuts the medium after printing in a width direction of the medium orthogonal to a transport direction of the medium, the printing device capable of performing printing on the medium by the printing mechanism and transporting the medium toward the cutting mechanism even during the cutting of the medium by the cutting mechanism. A printing device (1) includes a tension applying mechanism (10) having a tension bar (9) that comes into contact with a medium (2) after printing to apply tension to the medium (2). The tension bar (9) is disposed between a printing mechanism (3) and a cutting mechanism (7) in the transport direction of the medium (2).

The separator production method in accordance with an embodiment of the present invention includes a coated article winding off step of winding off, from a core, a separator original sheet which has been taken up in a coated article taking up step of winding the separator original sheet on an outer peripheral surface of the core while oscillating the core in a rotation axis direction, and the core is oscillated in the rotation axis direction in the coated article winding off step.

A post-processing device includes a sheet transporting section that transports one or more sheets, a cutting section that cuts the sheet along a transporting direction of the sheet being transported by the sheet transporting section and a paper piece transporting section that transports a paper piece cut by the cutting section, and a transporting speed of the paper piece transporting section is set lower than a transporting speed of the sheet transporting section.

A booklet making method includes: cutting a web of paper on one side and on another side into first and second continuous sheets, alternately bonding the first and second continuous sheets widthwise with a setting paste and a throwaway paste to form a double set continuous sheet of paper, and cutting the double set continuous sheet of paper into split double sheets of a selected longitudinal length. A plurality of split double sheets is integrally bound with an integrating paste to form a booklet-like product. Portions of the booklet-like product which are pasted and bonded with the throwaway paste are cut off to provide a plurality of booklets. Thus, by the booklet making method, booklets having an odd number of leaves or pages are formed without waste of paper and with reduced paper jams.

The present invention relates to a rewinding machine equipped with a support system for the reel and the ribbon-like product.

In particular, the invention relates to a rewinding machine (1) for a ribbon-like product (N), comprising: a fixed support structure which supports an unwinding unit (SV) and a rewinding unit (RB); an independent first carrier roller (2), movable along a direction parallel to a support surface of the rewinding machine (1); a second independent carrier roller (4), movable in the opposite direction with respect to the first carrier roller (2); a third roller (3), placed between the first (2) and second (4) carrier rollers and movable integrally with the first carrier roller (2); a set of driving rollers (110) placed along a path between the unwinding unit (SV) and the rewinding unit (RB); a web (10), forming at least one loop, made of a material with an air-permeable texture, said web (10) unwinding between the second carrier roller (4), the third roller (3), and the set of driving rollers (110); one or more suction boxes (6) placed under the web (10) to retain the ribbon-like product (N).
