摘要： PROBLEM TO BE SOLVED: To provide a winder for automatically winding a thick sheet such as a plastic foam sheet onto a paper core capable of completing transfer of winding in a short time without deteriorating the line speed of a manufacturing process. SOLUTION: A turret comprises a rotation shaft 41 and two side plates 42A and 42B installed on both ends of it. To shaft holes 43A and 43B provided at mutually corresponding positions in both side plates, two paper core fixing shafts 8A and 8B can be inserted from the outer side inward without reaching 1/2 of span S of the turret at respective tips. These are provided in such a way that constraint relation is generated between the paper core fixing shafts 8A and 8B and the paper core by swelling of the paper core fixing shafts when they are inserted into the paper core. To a specified combination of the paper core and the paper core fixing shaft at a winding position, a paper core rotating drive shaft actuates to rotate the combination to cause winding. When it gets apart from the winding position, the rotation drive shaft stops actuation on it.

摘要： PROBLEM TO BE SOLVED: To provide a curing sheet, to which anti-slip properties are applied, obtained by reducing the easy-to-slip properties being the flaw in a case used as various curing materials of plastic corrugated cardboard, which comprises two-layered constitution wherein a cap sheet having a large number of dents and a flat back sheet both of which are made of a plastic material such as polyethylene or the like are laminated along the surface of the bottom part of the cap sheet or three-layered constitution wherein a flat liner sheet is laminated to the surface formed by joining the apexes of the caps of the cap sheet in addition to the two-layered constitution, to a degree not becoming a problem from a practical aspect. SOLUTION: A curing sheet to which anti-slip effect is applied is obtained by bonding a lace-like sheet, which is produced from an olefinic elastomer like an ethylene/propylene copolymer, to the surface, which is formed by joining the apexes of caps, or liner sheet and back sheet of plastic corrugated cardboard. If it is unnecessary to bond the lace-like sheet to both surfaces of plastic corrugated cardboard, the lace-like sheet may be bonded to either one of both surfaces of the plastic corrugated cardboard.

摘要： PROBLEM TO BE SOLVED: To prevent harmful substances such as dioxines or the like from being produced at the time of incineration. SOLUTION: A paper-made shock dampening material 1 is formed of a pulp forming material containing pulps as its major substance, a binder for connecting pulps to each other and an antichlor. As antichlor, calcium carbide can be applied, and iron oxide can be added to the pulp forming material. Chlorine and the like contained in incineration gas can be removed and combustion characteristic can be improved by iron oxide, so that it is possible to prevent dioxides and the like from being produced at the time of incineration. In addition, paper-made shock dampening material is manufactured by a dry mold processing method to enable much amount of antichlor to be contained in the paper-made shock dampening material.

摘要： PROBLEM TO BE SOLVED: To obtain a foamed cushion improved in a cushioning effect, degradability, mechanical strengths, and workability by forming many cuts on the flat surface of a foam made from a degradable resin and opening the cuts to allow the foam to develop expansibility. SOLUTION: Cuts 12 spaced at constant intervals in a pattern of stitches are formed on the surface of a flat foamed sheet 11 containing starch or cellulose acetate as a base, 50-5 wt.% polyvinyl alcohol, polypropylene, or aliphatic polyester or 50-5 wt.% glycerol, kaolin, fat, protein, or a mixture thereof, 20-5 wt.% polyethylene, and 0.5-10 wt.% fibrous material as a reinforcement. The sheet 11 is stretched in the directions shown by the double-head arrow to obtain a net-like degradable foamed cushion. This cushion has quality and workability equivalent to those of a net-like foamed cushion chiefly made from e.g. polyethylene and, besides, it does not adversely affect the ecosystem.
