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： A method of slitting a continuous thermoplastic film comprises advancing the film longitudinally at a first speed along a peripheral surface of a roll rotating at a peripheral speed equal to or slightly greater than that of the film, and slitting the film while being advanced by pressing cutting edges of a rotating cutter against the peripheral surface of the roll. In order to prevent the cutting edges from being worn out and to form slits of uniform size and shape, the peripheral surface comprises an elastic layer of polymeric material, the cutting edges are heated above a temperature at which the film starts melting, the film and the elastic surface layer are cooled along their contacting surfaces with a cooling liquid, and the cutting edges are rotated at substantially the same peripheral speed as the roll. The invention also includes an apparatus for carrying out the method.

摘要： A non-woven fabric having a strength which is comparable to the strength of woven fabric and a method of making such non-woven fabric are disclosed. The non-woven fabric has a laminated structure composed of a warp web of random-laid non-woven fabric stretched lengthwise and hence having a greater strength in the lengthwise direction than in the transverse direction, and a weft web of random-laid non-woven fabric stretched transversely and hence having a greater strength in the transverse direction than in the lengthwise direction. Filaments constituting each of the warp and weft webs are substantially free from molecular orientation and extendible at least two times the original length before the web is stretched. Upon stretching of the web, the un-oriented filaments are substantially stretched to thereby cause molecular orientation therein.

摘要： A method and apparatus for stretching a thermoplastic polymer film in which the opposite selvages of the film are gripped by gripping means and are stretched transversely during heating by moving the selvages along two divergent arcuate paths lying in the same plane and extending over a predetermined circumferential range from a quater to a half of the full circumference of the circle containing the arcuate paths. In order to avoid drawbacks in the existing equipment such as irregular molecular orientation in and rupture of the film, the longitudinal travel of the film while being stretched is controlled by controlling means so that the central web portion is advanced by substantially the same distance as the gripped film selvages, whereby the amound of longitudinal movement of the film is held always constant throughout the width of the film.
