Abstract: A packaging and sealing apparatus has an opening mechanism for forming the package forcibly to an open configuration, an inserting mechanism for inserting the product into the package which has been formed by the opening mechanism, an open end forming mechanism for forming flatwise an open end of the package with the product inserted therein, a folding mechanism for folding the flatwise formed open end into a folded end, and a sealing mechanism for fixing the folded end. The opening mechanism, the inserting mechanism, the open end forming mechanism, the folding mechanism, and the sealing mechanism are successively arranged along a direction in which the package is conveyed by a conveyor.

Abstract: A magazine for admitting a roll of photosensitive material for photographic printer in a drawable state which comprises, a lightproof box made of paper, a cylindrical member made of paper which is provided in said box and which rotatably supports said roll of photosensitive material, and a support member made of paper which supports said cylindrical member.This magazine is a drawaway type, and it can be manufactured easily and inexpensively. It is easy to use, and there is no problem in its waste treatment.

Abstract: This invention depicts a web winding apparatus for winding belt-like materials (webs) such as plastic films, paper, thin metallic strips, which are slit to a predetermined width by a slitter. This web winding apparatus has at least one winder unit detachably mounted to a main body of winding apparatus. The or each of the winder units includes a support beam detachably mounted to the main body of winding apparatus, a plurality of pairs of arms provided on the support beam, for holding reels to wind slit webs from opposite sides and winding tension generators provided on the support beam corresponding in number to the reels, for giving a winding tension to the reels. A plurality of winder units are prepared in advance having the aforesaid arrangement, having various arm intervals arranged to accommodate to the widths of the slit, whereby winder units corresponding to the widths of webs are mounted to the winding apparatus.
