摘要： When producing plastic cards, a plurality of layers is laminated under application of heat and pressure resulting in unpredictable shrinking. In order to compensate shrinking, the laminated web is elongated to adapt to its nominal alignment size. Elongation is produced by material displacement along grid bars separating to-be-fabricated cards later punched off the web leaving a waste grid.

摘要： An oriented polymeric in-mold label film comprises a hot-stretched, annealed, linerless self-wound film lamina and has a face layer for printing and a base layer which includes a heat-activatable adhesive. The heat-shrinkability of the film is balanced thickness-wise to minimize curl and allow the film to be printed in conventional label-printing presses. An antistat may be included only in the charge for the base layer which includes the heat-activatable adhesive. In the manufacture of labelled blow-molded containers, sheets and labels formed from the film may be handled at high speeds while maintaining accurate registration and dimensional and positional integrity even in the absence of any reinforcing backing, yet the labels perform well on deformable containers such as shampoo bottles.

摘要： A process for forming intermediate sheeting for forming shaped interlayer blanks comprising extruding plasticized polyvinyl butyral melt into an endless straight-sided sheet having a gradient color band extending along one side, the melt forming the region of the sheet laterally of the color band extruding at a greater thickness than that forming the portion containing the color band, thereby providing a wedge-shaped thickness profile in the sheet, quenching the extruded sheet to set the polymer and winding the sheet in roll form. The intermediate sheet is at least about twenty inches wide and the wedge-shaped cross section gradually increases from about 28 to 32 mils at one edge to about 33 to 40 mils at the other edge.

摘要： The invention relates to stretching of a continuous web of a thermoplastic sheet, such as polyvinyl butyral sheet, having straight longitudinal edges into an arcuate form to use it as an interlayer of curved and laminated windshields of vehicles. Usually the web has a colored band to serve as a glare shield band along its one longitudinal edge. First the web travels vertically downward and is heated from its both sides by a vertical heater to produce a gradient of temperature across the width of the web such that the temperature at the web edge remote from the colored band becomes higher than the temperature at the opposite edge. Under longitudinal tension the heated web is passed around a first heated tapered roll and then around a second heated tapered roll having a higher temperature. Over these tapered rolls the web edge remote from the colored band is located relatively near the large diameter end of each tapered roll. The web stretched by the two heated rolls is successively passed over a plurality of cooled tapered rolls. By this method the web is smoothly stretched into a desired arcuate form without appearance of defects such as wrinkles or streaks on the stretched web.

摘要： Apparatus and method for producing a novel drawn film by propelling individual carriages along opposed loops from a first speed abutted in stacks in carriage collection sections to a second speed space apart in a drawing section of a tenter frame and to a third speed in stack forming sections where the carriages return to the first speed in the stacks. First primaries positioned adjacent one part of each loop develop electromagnetic waves for engaging synchronous secondaries attached to active carriages to provide controlled spacing of such carriages, and second primaries adjacent another part of the loop develop other electromagnetic waves for engaging hysteresis secondaries attached to active and to passive carriages to provide controlled abutting of the carriages.

摘要： A process is provided for producing a rolled thermoplastic resin film or sheet having a small difference in mechanical strength between the longitudinal and lateral dimensions of the film or sheet comprising rolling a thermoplastic resin material at least once by means of a pair of rolls arranged obliquely to the advancing direction of the resin material, followed by further rolling at least once the resulting film or sheet by means of another pair of rolls arranged obliquely to the advancing direction of the material, but symmetrically opposite to the former oblique arrangement, the temperature of the rolling and further rolling being room temperature or higher and lower than the melting point or softening point of the resin material, and the distance (d.sub.1) between the lateral end parts on one side of each pair of rolls which first contact the resin material being less than the distance (d.sub.2) between lateral end parts on the opposite side of each pair of rolls.
