    摘要： Apparatus and methods are provided for the embossing of a sheet of flexible graphite material between a pair of embossing rollers. The embossing rollers include a primary embossing roller and a backup roller. The primary embossing roller has an embossing pattern defined thereon. One or both of the rollers include a raised stabilization area adjacent a periphery of the embossing pattern. The raised stabilization area preferably has a roughened outer surface for better gripping the sheet of flexible graphite material. The raised stabilization areas apply a stabilizing force to the sheet adjacent the periphery of the embossing pattern, thereby limiting egress of the material laterally away from the embossing pattern. The roughened surfaces increase the grip of the raised areas upon the sheet, thus aiding in pulling the sheet between the rollers and also aiding in the application of lateral stabilization forces to the sheet.

    摘要翻译： 提供了设备和方法，用于在一对压花辊之间压花一片柔性石墨材料。 压花辊包括主压花辊和支撑辊。 主压花辊具有限定在其上的压花图案。 一个或两个辊包括邻近压纹图案的周边的凸起的稳定区域。 升高的稳定区域优选具有粗糙的外表面，以更好地夹持柔性石墨材料片。 凸起的稳定区域对与压花图案的周边相邻的片材施加稳定力，从而限制材料从压纹图案侧向远离。 粗糙表面增加了片材上的凸起区域的抓握力，从而有助于将片材拉动在辊子之间，并且还有助于向片材施加横向稳定力。

    摘要： A pair of rotary die cylinders each removably mountable in a die stand by a pair of opposed arbor assemblies each with a separate spindle journaled in a separate carrier block and having a nose drawable into engagement with complementary recesses in opposed ends of the die cylinder in coaxial alignment with the axis of the die cylinder. The noses of the spindles are removably engaged in the recess by a drawbar extending through each cylinder. The carrier blocks are removably slidably received in slots in a pair of spaced apart uprights of the die stand.

    摘要： A web cutter includes a knife roll located above an anvil roll, a web infeed conveyor for moving a continuous web to be severed to the nip between the rolls and a segment discharge conveyor for removing segments cut from the web. The roll includes a plurality of fixed cutting knives and the anvil roll includes a plurality of fixed anvils such that rotation of the rolls brings each knife into engagement with an anvil to sever the web. Lift plates on the anvil roll are located immediately upstream from each anvil to raise the severed lead end of the web above the anvil in order to assure proper feeding to the discharge conveyor.

    摘要： A fiber bundle cutting device is disclosed which includes an elastic roller; a cutting roller having a plurality of thin plate-like cutter blades extending radially therefrom, the cutter roller being disposed in parallel relation with the elastic roller in such a manner that the cutter blades can be slightly pressed against a surface of the elastic roller; a plurality of push-out members each movably mounted between a respective pair of the cutter blades and disposed adjacent to one another; and ring members respectively holding the opposite ends of each of the push-out members to maintain the push-out members in a generally cylindrical configuration; the ring members and the push-out members held by the ring members being movable to an eccentric position relative to the cutter roller so as to progressively move from the proximal to the distal edge of the cutting blades during the operation of the cutting device to discharge the cut pieces of a fiber bundle.

    摘要： A roving cutter with a positive ejection cutting head in which the ejection elements provided in the spaces between the circumferentially spaced cutting blades are mounted in eccentrically rotating end places under axial tension so as to form with the end plates a squirrel cage-like rigid assembly. By placing the ejection elements under lengthwise tension they can be given the required rigidity in spite of being reduced in cross section, for example to take on the form of rods or wires. Because of this, longer cutters become possible and in cutters of conventional length greater clearances can be obtained and thus the build-up of fiber material or dust in the spaces between the blades more effectively avoided.

    摘要翻译： 具有正喷射切割头的粗纱切割器，其中设置在周向间隔开的切割刀片之间的空间中的喷射元件在轴向张力下以偏心旋转的端部位置安装，以便与端板一起形成鼠笼式刚性组件。 通过将喷射元件放置在纵向张力下，尽管横截面减小，但是它们可以被赋予所需的刚度，例如以棒或线的形式。 因此，更长的切割器成为可能，并且在常规长度的切割器中可以获得更大的间隙，因此更有效地避免了叶片之间的空间中的纤维材料或灰尘的积聚。

    摘要： A rotatable pin cylinder and a coacting backing or anvil roller define a nip through which die cut and creased sheet material is fed to have intervening waste pieces removed. A hollow cylinder or combing drum is telescoped over the pin cylinder for rotation about an axis which is eccentric with respect to the pin cylinder axis. The drum and cylinder and driven in unison and as they rotate through a complete cycle, radially projecting stripper pins carried by the pin cylinder are caused to project through apertures in the combing drum to impale and separate waste pieces from the sheet material in the area of the stripping nip. Thereafter the pins are progressively retracted within the periphery of the combing drum to positively eject the waste pieces in an area approximately opposite the stripping nip.

    摘要： The present invention relates to highly permeable film products and a method for the production of such products comprising continuously passing relatively unpermeable, unperforated film stock through the nip of a pair of counter-rotating rollers. One of the rollers, i.e. a perforating roller, is provided around the circumference thereof, with a plurality of relatively dull needles or brads which serve to puncture the film as it passes through the nip formed by the perforating roller and a second back-up roller. As the film is being perforated it is firmly anchored and supported in a transverse direction by both the back-up roller and a resilient elastomeric material positioned around the periphery of the perforating roller, whereby efficient and positive film perforation is achieved at high film throughput rates.
