Abstract: The first-state jacketed roller in an apparatus for spin drawing synthetic fiber comprises a roller rotatably mounted on a shaft and encompassing a fixed, non-rotatable inner core. The roller includes an electrically conductive tubular member coaxial with, and hermetically affixed to, the inner wall of the roller. A plurality of bore holes extend in the conductive member parallel to the roller axis and are coextensive therewith, and a heat transfer fluid fills each bore hole. The fluid divides into a liquid and a vapor phase when the roller is heated and rotation of the roller forces the liquid phase outwardly under centrifugal force into engagement with the outer portion of each bore hole.

Abstract: A device for producing an obliquely oriented film of thermoplastic synthetic resin comprising an extruder, an annular die for forming the resin extruded from the extruder, a first mandrel, a second mandrel, and drawing rolls for drawing the resinous film passed over the first mandrel and then second mandrel. Said first and second mandrels are rotated in the different directions from each other.

Abstract: Improved apparatus for treating a web of fibrous material, usually paper, to render it particularly suitable for making filter plugs for cigarettes, including at least one first pair of meshing rotating rolls provided with longitudinal grooves alternating with longitudinal ribs, which engage the paper and stretch it longitudinally in closely spaced successive narrow transverse areas to loosen and expose fibers without impairing the longitudinal continuity of the paper, and at least one second pair of meshing rotating rolls provided with circumferential grooves alternating with circumferential ribs, which engage the paper and groove it in a direction parallel to its travel while also stretching it transversely to further loosen and expose fibers without impairing the transverse continuity of the web. Preferably the apparatus also includes means for moistening the paper in advance of its passage through the rolls and for drying it after its passage therethrough.

Abstract: Internal mandrel process and apparatus for the production of oriented tubular film in which rupture of the extruded tube by the pressure of inflating gas is prevented by means of a cup seal located between the mandrel and inflating zone, the cup seal being in peripheral engagement with the internal surface of the tube and presenting a substantially concave surface of the mandrel.

Abstract: Apparatus for manufacturing synthetic tow for stretch-cut spinning process. This synthetic tow is produced by changing the coagulation condition after delivery from the spinnerets so the weak points are distributed in individual filaments in a particular condition defined by variation of unevenness of breaking strength. The coagulation condition of each filaments in the tow is positively changed according to periodic changes in the filament's passage by contacting a deviation bar disposed in the filament's passage.

Abstract: An apparatus is described for drawing at least one and preferably a multiplicity of continuous fibers through a drawing funnel. The drawing funnel is positioned with its inlet at a predetermined distance from the source from which monofilament is to be drawn. The funnel is provided with an aerodynamically smoothly converging inlet on an upstream section thereof. This converging inlet accelerates the flow of fluid, preferably air or other gaseous medium, and creates laminar flow of that fluid. Means are provided to establish a pressure differential over the length of the funnel and cause the fluid flow through the funnel. Laminar flow is utilized in the converging inlet and preferably over the length of the drawing funnel, to inhibit physical damage to the continuous fiber. The funnel inlet is located to insure that the fiber is fully solidified or finished, before a pulling force is exerted thereon.

Abstract: An improved process and apparatus for production of synthetic multifilamentary yarns having uniform quality. The method comprises extruding a molten synthetic polymer downwardly through a spinneret, advancing the extruded filaments downwardly through a substantially stationary column of heated air, and subsequently advancing the filaments downwardly through a quenching zone wherein they are in contact with cooling air introduced into the path of the filaments under controlled conditions of air velocity and direction of flow.

Abstract: A biaxial stretching machine has a return line for each row of grippers, the return line including a storage region defined by a section of storage track and a screw for feeding grippers to the storage track. The screw is of diminishing pitch and is axially compressible to vary the effective capacity of the storage region. In one form the return screw can be compressed by a spindle-nut-arrangement.

Abstract: The invention relates to apparatus for producing strudel dough and the like. The apparatus generally comprises rolling apparatus for rolling dough into a flat sheet, a conveyor and stretcher for conveying the dough from the rolling apparatus and stretching it in a direction transverse to the direction in which it is rolled, clamping and conveying apparatus for conveying the dough from the stretching apparatus while maintaining it in its substantially most stretched condition, and apparatus for facilitating the removal of moisture from the flat sheet to preferably reduce its moisture content 80-83%. The moisture removing apparatus may comprise a hot-air blower and/or an absorptive band or the like.
