    • An apparatus for forming a sheet of material from a supply of the material includes a pair of rotatable rolls that define a gap which forms the material into a sheet. The size of the roll gap is maintained constant during the sheeting operation despite forces exerted on the apparatus caused by inconsistencies in the material being sheeted. The apparatus has a force-applying mechanism which applies a selected amount of force against one of the rolls to bias the one roll toward the other roll, the amount of force being sufficient to overcome any force exerted on the apparatus by the material during sheeting, which forces would otherwise result in variations in the size of the roll gap and the thickness of the resulting product. The one roll is movably mounted in scissor-like fashion and is acted on by the force-applying mechanism in a direction which biases the one roll against the other roll.
    • 用于从材料供应源形成材料片的设备包括限定将材料形成片材的间隙的一对可旋转辊。 在片材操作期间,辊间隙的尺寸保持恒定,尽管施加在装置上的力由于被切片材料的不一致而引起。 该装置具有施力机构,其将一定数量的力施加到一个辊上以将一个辊朝向另一个辊偏压,该力量足以克服在片材期间材料施加在装置上的任何力, 否则这些力将导致辊间隙的尺寸和所得产品的厚度的变化。 一个卷筒可以剪刀式的方式可移动地安装,并且通过施力机构在一个辊对另一个辊子偏压的方向上作用。

    • An apparatus for forming a sheet of material, e.g., dough or masa, from a supply of the material includes a pair of rotatable rollers that define therebetween a gap into which is input a dough mass and out of which is produced a dough sheet. Fluctuations in the size of the roller gap are sensed by detecting changes in the position of one of the rollers, which changes are input to a servo system that automatically corrects the position of the one roller so as to maintain the proper gap size. The one roller is movably mounted in scissor-like fashion and is easily driven by a servo motor. A cutter is provided which presses against one of the rollers to cut individual dough portions from the sheet. The ends of the cutter are subjected to a bending moment which induces a camber in the cutter. This prevents the central portion of the cutter from bowing away from the roller and ensures uniform pressure between the cutter and roller, even for applications with an extremely long cutter and rollers.
    • 用于从材料供应源形成例如生面团或泥灰的材料片的设备包括一对可旋转的辊,其间限定有一个间隙,输入面团块并从面团制成面片。 通过检测一个辊的位置的变化来检测辊间隙的波动,该变化被输入到自动校正一个辊的位置以维持适当间隙尺寸的伺服系统。 一个滚筒可以剪刀式移动安装,并且易于伺服马达驱动。 提供了一个切割器,其压靠一个辊子,以从片材中切割各个面团部分。 刀具的端部受到弯曲力矩的影响,从而在刀具中产生弯度。 这样就可以防止切割器的中心部分从滚轴上弯曲,并确保切割器和滚筒之间的均匀压力,即使对于具有非常长的切割器和滚筒的应用也是如此。
