摘要： Polymeric film is stretched by pulling the film over a first roller which is heated and over a second roller which is cooled, the second roller rotating at a greater peripheral speed than the first roller. The necking-in of the film in the gap between the two rollers is considerably reduced if a heat-transfer liquid is applied betwen marginal portions only of the film and the corresponding peripheral portions of the second, cooled, roller.

摘要： A method and apparatus for biaxially drawing plastic films wherein a plurality of carriages carry clamps for grasping the edges of a film to be drawn, the carriages each carrying an armature and movable along guide tracks through a drawing frame. A plurality of field windings are longitudinally spaced along each of the guide tracks such that the field windings and the armature cooperate to form a series of linear motors whereby the speed of individual carriages is independent of other carriages. The guide tracks have diverging portions wherein the film may be simultaneously laterally and longitudinally drawn by controlling the speed of the carriages.
摘要翻译：一种用于双轴拉伸塑料膜的方法和装置，其中多个托架携带用于抓握要拉制的膜的边缘的夹具，每个托架承载电枢并且可沿引导轨迹移动通过绘图框移动。多个励磁绕组沿着每个引导轨道纵向地间隔开，使得励磁绕组和电枢协作以形成一系列直线电动机，由此各个滑架的速度独立于其它滑架。导轨具有发散部分，其中胶片可以通过控制滑架的速度同时横向和纵向拉伸。

摘要： Molded seamless brassiere pads or cups made from thermoplastic adhesive bonded nonwoven fibrous batting and an apparatus and method for molding the same without thinning of the crosssectional area of the apex portion of the brassiere pad or cup relative to the cross-sectional thickness of the remaining wall portions of the pad or cup. To this end a central portion of the blank from which the pad is molded under heat and pressure is subjected prior to the molding operation to the action of a coolant to prevent the thermoplastic adhesive bond in the bonded nonwoven fibrous batting from being softened during the molding operation. The thus cooled central portion of the body of the blank is held in position in the mold by piercing elements mounted on the male mold member and which project into the loosely arranged fibers in the cooled central area of the inner surface of the body of the blank without forming unsightly or objectionable holes or other marks therein. A molded seamless brassiere pad or cup is formed in which the cross-sectional thickness of the apex portion of the pad or cup is not reduced relative to the cross-sectional thickness of the remaining wall portions of the pad or cup and the apex portion of the pad or cup is not otherwise weakened.

摘要： A film is made of an elastic material. The film is stretched in at least one direction in parallel to a surface of the film. Then, through-holes are punched in the film be means of needles, in a state the film is stretched. After the punching is completed, the stretching is terminated, so that the film recovers its original shape.
