Abstract:
The invention is a polyester composition containing crosslinked polymer particles with ester bonds at the main chain. The particles are excellent in affinity to polyesters, and so the films formed from the polyester compositions do not have the particles falling off during high speed running, and do not have flaws in the film surfaces. The invention can prevent the generation of white powder and the flaws of magnetic faces caused by falling-off particles, and prevent the contamination in the production of films, even though these are problems caused when various conventional particles are added, and is especially suitable for use as products such as magnetic films.
Abstract:
A post-processing apparatus including: a conveyance unit which conveys a sheet, having been carried-in, to a selected conveying destination among a plurality of conveying destinations; a stiffness imparting unit which imparts stiffness to the sheet being conveyed by the conveyance unit; and a control section which controls the stiffness imparting by the stiffness imparting unit, wherein the control section controls whether to impart or not to impart stiffness to the sheet, according to the selected conveying destination.
Abstract:
A sheet processing apparatus, including a sheet processing section which performs predetermined processing on sheets of paper to form a booklet; a booklet ejection section which nips the booklet and ejects the booklet outside; an ejected paper stacking section on which the booklet ejected by the booklet ejection section is stacked; a shutter section which is provided between the booklet ejection section and the ejected paper stacking section and is openable and closable; and an opening and closing mechanism which performs an opening and closing operation that is opening the shutter section when the booklet is ejected by the booklet ejection section and closing the shutter section after the booklet is ejected.
Abstract:
Sheets center-folded by a center-folder are placed on a main saddle. A buffer saddle is provided separately from the main saddle, on an opposite side of the center-folder across the main saddle. The pile of sheets saddle-stitched on the main saddle is placed on the buffer saddle. When viewed from above, the buffer saddle is movable in a direction separating from the main saddle that is a reverse direction to the center-folder, and in a direction orthogonal to the direction separating from the main saddle. A sheet processing device is arranged in the orthogonal direction where the buffer saddle is movable.
