摘要： A pair of stretching pulleys are rotatably mounted on a pair of support plates within a housing. A belt is wound around the upper part of the stretching pulley and a number of turn pulleys. A film introduced onto the stretching pulley is held between the belt and the stretching pulley and is transferred. Air flow generated by a fan and heated with a heater is blown against the film through a louver and circulates through bellows mounted to the housing to return to the fan. The stretching pulley is partially cooled in a water bath. The support plates are rotatably connected to screw shafts, thereby changing a distance and angle between the plates. The stretch width or stretch ratio of the film is thus adjusted with the change of the distance and angle.

摘要： A rotary splitting tool for splitting a web of plastic material to fabricate a fibrillated web, comprising a rotatable body having a plurality of transverse ridges provided on the periphery in a circumferentially equidistant relationship and extending generally parallel to the central rotation axis, and rows of cutting edges provided on the transverse ridges, respectively. Convex walls are provided on the periphery of the body between the adjacent transverse ridges. The convex wall means receives a web to be split so that oscillation of the web during repeated operations of the cutting edges can be minimized to reduce noise and prevent irregular slits.

摘要： In a method of and an apparatus for heat-setting a non-woven fabric in which a warp web and a weft web is cross-laminated, the fabric is gripped at least at its opposite side edges by and between an outer peripheral surface of a hot cylinder and an endless belt normally tensioned against that outer peripheral surface. Widthwise shrinkage is fully prevented during travel of the fabric around the hot cylinder, and firm bonding of the warp and weft webs is attained.

摘要： Longitudinal and transverse stretching of a tubular film is effected by gripping opposite selvages of the tubular film between a pair of substantially coplanar pulleys and a pair of endless belt means trained arcuately around the pulleys, respectively, and by rotating the pulleys at a peripheral speed greater than a speed of feed of the tubular film. As the film selvages progress along a pair of arcuate divergent paths, respectively, around the pulleys, the film is heated, reversed in direction of travel, and cut along the selvages into a pair of biaxially stretched sheets. Before stretching of the film, live steam is introduced into the tubular film for heating the same.

摘要： An ultra-high molecular weight polyolefin having a viscosity average molecular weight of at least 500,000 is subjected to melt forming into a film, the thus obtained molten film or solid state film is transversely stretched while holding both the side edges of the film, the stretched film is longitudinally slitted into tapes, and then the thus obtained tapes are longitudinally stretched thereby to produce high-strength yarns easily. A number of slits are longitudinally or transversely made in films made of an ultra-high molecular weight polyolefin having a viscosity average molecular weight of at least 500,000 so that the films each take a meshy form when spread in the direction perpendicular to the slits, and the meshy form structures are stretched in the direction of the slits to prepare meshy webs having a high strength unidirectionally. At least one member selected from the thus prepared meshy webs is used as one nonwoven web, thereby producing a high-strength, web-crossed laminated nonwoven easily.

摘要： A device for transversely stretching a web includes a pair of pulleys arranged in the substantially same plane and rotating in the opposite directions to each other and a pair of belts running around the pulleys, respectively. The web is widthwise stretched, by gripping opposite side edges thereof by the pulleys and the belts and conveying the web in a divergent manner. At least one pair of pressing rolls are provided at an inclination relative to the belts for pressing the opposite side edges of the web onto the belts prior to being gripped between the pulleys and the belts. According to this structure, a device for transversely stretching a web is realized which is capable of effectively preventing the web from being dropped from the grip.

摘要： A web spreading apparatus for transversely spreading a web, such as a split web formed of a longitudinally uniaxially stretched film, includes a spreading means arranged in a travelling path of the web for transversely spreading the web. The spreading means comprises a curved rod-like member and projections arranged generally circumferentially about an axis of the curved rod-like member. The curved rod-like member is arranged so that the concave side is directed forward and the convex side is directed rearward, in the web travelling direction, and the projections are rotatable about the axis of the curved rod-like member at a speed higher than the travelling speed of the web. In one aspect, the curved rod-like member comprises a curved shaft and an outer tube arranged about the curved shaft and rotatable relative to the curved shaft, the projections being formed between the grooves cut on the outer tube. In another aspect, the projections are formed of a spring arranged about the curved rod-like member.
