Abstract: A sewing machine attachment (12) for sewing a label to a workpiece or sewing other 360 degree operations having a sliding cloth plate (22), cloth clamps (24 and 26), a backup clamp (32) and a template (30) for clamping the workpiece and label is disclosed. The template has first and second peripheral surfaces, and at least part of the contour of the first peripheral surface in a first position substantially aligns with at least part of the contour of the second peripheral surface in a second position. The template is moved between the first position and the second position during the 360 degree operation.
Abstract: An automatic apparatus for sewing elongated workpieces, and especially useful for precisely sewing a pair of concealed slide fastener stringers to a pair of fabric halves defining the opening therebetween comprises a table having fabric input guides at the front end of the table, a sewing station, and a gripper assembly for drawing the fabric pieces from the sewing station under a tension less than that applied by the sewing machine feed dog and presser foot. Individually actuable workpiece holders are provided to permit successive setting up of the fabric pieces in the sewing station. Fastener stringers are guided to the sewing station with their corded edges supported in guide channels as the stringers are superposed on the respective fabric piece. The sewing operation proceeds automatically in an extremely precise manner after the sewing station is inputed and the sewing machine started.
Abstract: A button-sewing machine (1) comprises a needlebar frame (6), which is suspended like a pendulum and connected to a rocking linkage (8). A button-holding clamp (5) is tiltably mounted in a stand (4), which is carried by a base plate (3), which is mounted on the machine base (2) and longitudinally displaceable relative to said machine base and longitudinally reciprocable by an actuating head (9). The latter is operatively connected to the main shaft of the machine.The machine can be used to perform several different working programs without an alteration of the machine. For this purpose the stand (4) is transversely movable relative to the baseplate (3) or the baseplate (3) is adapted to perform relative to the machine base (2) not only a longitudinal displacement but also a transverse angular movement. A coupling element (19) is provided, which is operable to selectively couple the actuating head (9) either to the baseplate (3) or to the rocking linkage (8) of the needlebar frame (6).
Abstract: A workholder for a sewing machine for producing a stitch row in a workpiece according to a predetermined contour. The movably arranged workholder has a cutout essentially formed according to the stitch contour and is controlled with respect to the needle by means of a feeding device incorporating a linkage system and a control disc. In particular, a new frame-type workholder with an additional workpiece clamp is provided for rendering possible the production of a decorative stitch row in connection with a label fastening stitch row.
Abstract: Sewing labels on a sewing machine having a label feed attachment is provided by a pair of clamp members. The clamp members are pivotably joined at one end to open and close at the other end and are conjointly movable in a path parallel to the path of movement of the material from a first position corresponding to the point at which the labels enter the path of movement of the material to a second position corresponding to the mouth of said presser foot. The labels are grasped and moved by the clamp members into contact with said material and held thereto by a cooperating feed mechanism and presser foot for sewing.
Abstract: A low inertia drive mechanism is disclosed for imparting translational movement to a sewing machine fabric clamp. The drive mechanism comprises a first and second rigid tables mounted on guide rods for independent translational movements in mutually perpendicular straight paths. The second table carries a pair of transverse rods on which a third rigid table is slidably mounted which may move in any direction in a plane parallel to the planes of said first and second tables. The drive mechanism also comprises stationary motors not carried by any of the tables for imparting reciprocatory motion to the first and second rigid tables. The mechanism further includes means for connecting the fabric clamp to the third rigid table.Also disclosed is a fabric clamp for supporting and guiding fabric for use with a variable translation fabric feeding mechanism.
Abstract: An automatic necktie neckband tacker, comprising a guage having inner peripheral edges defining an opening substantially equal to the size of a neckband for securing a neckband therein, an upper clamp forming a clamp opening therein substantially equal to the opening of the gauge and aligned therewith, the upper clamp moveably disposed above the guage constituting a clamping unit therewith for clamping therebetween a tie at a neck area thereof adjacent the neckband, and a clamp and cutting blade carrier for clamping and cutting, respectively, an upper needle thread. The upper clamp has a formation for guideably mounting the clamp and cutting blade carrier for movement of the latter upon actuation thereof into a withdrawn position under the upper clamp, as well as into an operative position projecting into the clamp opening. A pneumatic cylinder is operatively mounted on said upper clamp moveably jointly therewith, for actuating the clamp and cutting blade carrier.
