摘要： An apparatus for use with a sewing machine having a frame for supporting a tubular workpiece that is movable between a workpiece loading station and the sewing area of the machine. The workpiece is supported under tension on the frame which includes a positioning element for locating it thereon and a folding element for folding one of its ends over an elastic band placed on the workpiece at a predetermined distance from the positioning element. Movement of the frame to the sewing area places the workpiece in position to receive a seam of stitches in the folded portion within which the elastic band is located.

摘要： A device for sensing the removal of workpieces from a stack by a pickup head which, during its intended function, is lowered to engage the upper workpiece in a stack, then elevated to remove the workpiece and then rotated so the workpiece can be deposited in a preselected location. The sensing device is pivotably mounted on the pickup head and movable between positions below the underside of the pickup head when the latter fails to engage a workpiece and at a level even with the underside of the pickup head which is accomplished through its engagement with a workpiece held by the pickup head. Upon engagement and pick up of a workpiece, a signal is given to raise the pickup head and then rotate it so the workpiece can be deposited in a predetermined location. Upon failure to engage and remove a workpiece from a stack, a signal is given for the pickup head to make a plurality of repeated attempts to engage and remove a workpiece from the stack. After a predetermined number of failures of the pickup head to perform its intended function, a warning signal is activated for the purpose of drawing attention thereto.
摘要翻译： 一种用于感测通过拾取头从堆叠中去除工件的装置，其在其预期功能期间被降低以将堆叠中的上部工件接合，然后被提升以移除工件，然后旋转，使得工件可以沉积在 预选位置 感测装置可枢转地安装在拾取头上，并且当拾取头的下侧不能接合工件时，在拾取头的下侧的位置之间可移动，甚至在通过其与工件接合而实现的拾取头的下侧 由拾音头持有。 在接合和拾取工件时，给出提升拾取头的信号，然后旋转它，使得工件可以沉积在预定位置。 在没有从堆叠中接合和移除工件时，给出拾取头的信号以进行多次重复尝试以从堆叠接合和移除工件。 在拾取头的预定数量的故障执行其预期功能之后，为了引起注意，激活警告信号。

摘要： A prepainted sheet metal bed cover attachable to a top portion of a sewing machine bed casting having a minimum of machining on an upper surface thereof. The bed cover rests on a machined raised peripheral rim on the upper surface, and is additionally supported on resilient non-metallic material deposited on pads interspersed on the upper surface which are machined to a level below the raised peripheral rim to accommodate the non-metallic material between the bed cover and the pads. The cover is firmly fixed to the top portion of the bed casting by a skirt portion of the prepainted bed cover which extends about the periphery of the top portion, and is swedged beneath the top portion of the bed casting to form a unitary assembly therewith.
