摘要： A multiple needle sewing machine having a shiftable needle mechanism wherein threaded needles may be shuttled from an active to an inactive position and vice versa. A thread wiping mechanism, comprising an arrangement of articulated fingers is disposed adjacent the needles' inactive positions. Upon a proper signal, the fingers extend to a position to await the inactive needle, whereupon, the fingers will be retracted, catching only the thread of the inactive needle holding it out of the way of the needle in the active position. The thread wiping mechanism may be actuated by reciprocable means attached to the fingers, which actuation occurs upon receipt of a proper signal during operation of the sewing machine.

摘要： An automatic sewing machine is provided wherein the clamps for holding the workpiece can be used to define at least two different sewing patterns. The sewing pattern which is particularly defined by a given arrangement of clamps is indicated to a digital control system within the sewing machine. The control system is operative to subsequently implement an automated stitching of the particular sewing pattern which has thus been indicated thereto. This automatic stitching is accomplished through a sequential reading of a set of instructions previously stored within a memory associated with the control system. The set of instructions remain the same for at least two different sewing patterns. These instructions are altered upon read out by certain control logic which takes note of which pattern has been defined by the given arrangement of clamps. The automated stitching is completed by an automatic ejection of the clamped workpiece.

摘要： A rigid, lightweight positioning system is disclosed for use with a high speed sewing machine. The positioning system includes a rigid, lightweight frame that is slidably mounted in a predefined plane. The frame is driven within the plane by a remotely located motor. A carriage is slidably mounted on the frame so as to move in a direction transverse to the direction of movement of the frame itself. This carriage is driven along its axis by a second remotely located motor. The overall arrangement of the elements within the positioning system is such as to minimize the introduction of vibration at the point of sewing.

摘要： A method and machine are provided for controlling the orientation of one or more sewing instrumentalities with respect to a workpiece while also controlling the path of movement of the workpiece. The one or more sewing instrumentalities are preferably rotated about an axis perpendicular to the plane in which the workpiece is moved. The invention furthermore provides for separate and independent control of each sewing instrumentality so as to thereby render one or both needles inoperative at various times during continuous operation of the machine. The invention still further provides for separate manipulation of the thread associated with each respective sewing instrumentality so as to allow for a pullback of this thread. In principle the invention is also applicable to other than sewing machines wherein one or more operative tools may, for example, perform such functions as marking, folding, pinking, or perforating.

摘要： A sewing machine having two needles supported in a needle holder, which needle holder is horizontally displacable, to present one needle to an active workstation in a prethreaded manner and simultaneously shift the other needle which has a different thread therein, into an adjacent inactive position. As the needles are being shifted, the needle moving to inactive status has its thread clamped against the needle holder by a wheel, to secure the thread from being pulled therefrom or straying. A vacuum tube arranged at each respective inactive position or station sucks the tail of the thread therein. A pair of thread guides, one for each thread, are arranged for vertical movement, to pullback on the dangling thread of the inactive needle, to prevent the thread from whipping during its inactive status. Each thread passes around a thread engaging wheel comprising a dual bobbin monitor arranged on a single axis. A thrust bearing is arranged between each thread engaging wheel and an adjustable knob is arranged to bias the sides of the wheels to allow each thread to have the same tension regardless of its current status, active or inactive. A wedge arrangement at the drive end of the sewing machine mates into a groove on a disk attached to the drive shaft which wedge arrangement, after stopping the drive shaft from rotating, then permits the shifting of the needles from active to inactive status. The wedge mating in the groove of the shaft insures proper alignment of the shifting mechanism permitting the shuttling of the needles from their inactive to the active position and vice versa.
摘要翻译： 一种缝合机，其具有支撑在针保持器中的两个针，该针保持器水平置换，以预先方式将一个针呈现到活动工作站，同时将具有不同螺纹的另一个针移动到相邻的非活动位置。 当针被移动时，针移动到非活动状态，其线被其轮缘夹紧在针架上，以固定线从其被拉或偏离。 布置在每个相应的非活动位置或站处的真空管吸引线中的尾部。 一对螺纹导向器（每个螺纹一个）被布置成用于垂直运动，以在非活动针的悬挂线上回拉，以防止螺纹在其非活动状态期间搅动。 每个螺纹绕过包括布置在单个轴上的双线轴监视器的螺纹接合轮。 推力轴承布置在每个螺纹接合轮之间，并且可调节旋钮布置成偏置车轮的侧面，以允许每个线圈具有相同的张力，而不管其当前状态是活动还是非活动。 在缝纫机的驱动端处的楔形装置配合到安装在驱动轴上的盘上的槽中，楔形装置在使驱动轴停止旋转之后允许针从活动状态移动到非活动状态。 在轴的凹槽中的楔配合确保了换档机构的正确对准，允许针穿梭从不活动到活动位置，反之亦然。
