    • An apparatus for forming a spread of generally thin, pliable material from a roll thereof onto a table includes a cradle for holding the roll of the material which is selectively operable to rotate the roll of material for feeding a web of material generally forwardly from the roll. An endless conveyor including a series of flights spaced at intervals therealong with openings between the flights is driven for forward travel, and the web from the roll of the material is received on and carried forward by a flight in the upper reach of the conveyor. A knife is operable to cut the web to separate a first sheet of material from the roll of material. The first sheet of material is thereafter held from forward movement with the supporting flight by grippers selectively operable for gripping the first sheet of material on the supporting flight in the upper reach of the conveyor. Thus, the supporting flight slides out from under the first sheet of material with the first sheet falling onto the table.
    • 用于将从其辊形成的普通薄的柔韧材料的铺展物形成在桌子上的装置包括用于保持材料卷的支架,该托架可选择性地可操作以旋转材料卷,以从辊总体上向前馈入材料卷材 。 一种环形输送机,包括一系列间隔开的间隙,其间具有间隙的开口被驱动用于向前行进,并且来自材料卷的卷材通过输送机上部的飞行物被接收并在其上承载。 刀可操作地切割幅材以将第一片材料与材料卷分离。 此后,第一片材料由向前的运动保持,支撑飞行通过夹持器选择性地可操作地夹持在输送机的上部范围内的支撑飞行上的第一片材​​料。 因此,支撑飞行物从第一张材料下方滑出,第一张纸落在桌子上。

    • The present invention relates to a method and apparatus for cutting pieces of fabrics of uniform thickness and for stacking these pieces. The method generally includes arranging and maintaining a length of unrolled fabric on a cutting table which comprises a revolving cylinder which rotates so that the length of fabric is positioned to face a cutting instrument. The fabric is cut out according to one or more predetermined patterns when the cylinder stops rotating. Displacement of the cutting instrument over the circumference of a cylinder follows the generators of the cylinder during its motion. After the fabric is cut, the cylinder rotates to deposit the cutout pieces onto a fixed or mobile receiving/stacking table which is positioned under the cylinder. During such deposition, a new length of fabric is simultaneously arranged on the cylinder preparatory to being cut. Alternately, a conveyor belt can be used in lieu of the cylinder.
    • 本发明涉及一种用于切割均匀厚度的织物的方法和装置,并且用于堆叠这些片。 该方法通常包括在切割台上布置和保持展开的织物的长度,该切割台包括旋转的圆筒,旋转圆筒使得织物的长度定位成面对切割器具。 当气缸停止旋转时,根据一个或多个预定图案切割织物。 切割仪器在气缸圆周上的位移跟随气缸在其运动过程中的发生器。 在织物切割之后,滚筒旋转以将切割片沉积到定位在圆筒下方的固定或移动的接收/堆叠台上。 在这样的沉积期间,新的长度的织物同时布置在准备切割的圆筒上。 或者,可以使用传送带代替气缸。
