Abstract: The present invention provides a sewing machine enabling to sew a high-quality pattern without using an embroidery frame. In a sewing machine 1, a pattern is sewn while a fabric 100 is fed in a sewing direction by a feed dog 2a. The sewing machine 1 has a fabric guide 14. The fabric guide 14 has a guide portion 16 which extends straight in a sewing direction to serve as a basis of a cloth feed in an amplitude direction of the needle. The carriage 10 makes the fabric guide 14 slide in the amplitude direction of the needle by a predetermined distance. Thus, the guide portion 16 serves as an index of the position of the fabric 100 to be located for sewing the next pattern line. Since the fabric 100 can be accurately located for sewing the next pattern line, high-quality pattern can be sewn.

Abstract: An embroidery frame includes a holding member configured to hold a sewing workpiece, an attaching member connected to the holding member and is detachably supported in a specified mounting position in relation to a frame support member provided in a sewing machine, and a positioning member mounted on the attaching member and including second engaging portions and displaceable portions. When, in the specified mounting position, the second engaging portion is engaged with first engaging portion, horizontal movement of the attaching member is restricted. When the displaceable portion is positioned in a first position, the horizontal movement of the attaching member is restricted by the engaging of the second engaging portion with the first engaging portion provided on the frame support member, and when the displaceable portion is positioned in a second position, the restricting of the horizontal movement of the attaching member is undone.

Abstract: An apparatus and method for accurately aligning the top and bottom edges of a garment's workpieces to assure even cuffs after sewing, the apparatus comprising two locking jaw assemblies which cooperate with drive rollers (all of which are located upstream of the sewing head) and the conventional bottom feed action of the lower feed dogs on a sewing machine to capture any excess length or slack of the garment's panels between the locking jaws (to match the cuffs ) and then to drive any excess slack out of the panels as they are fed to the sewing head to be sewn.

Abstract: A sewing device for sewing an elastic band to cloth. The sewing device includes a pair of spaced fingers slidably connected one with the other, a spring-loaded pin fixed to one finger's slide bar that cooperates with one of a series of holes in the finger's slide bar to hold the fingers in desired spaced relation, and a removable spring clip that cooperates with each of the fingers to hold an elastic band in connected relation with those fingers when desired. In use, and with the fingers spaced a minimum distance one from the other, the elastic band is laid over the fingers and connected thereto by the spring clips. The spring-loaded pin on one slide bar is then depressed to move it out of a hole in the other slide bar, the slide bars thereafter being moved relative one to the other until the fingers are spaced that distance which provides the desired stretch in the elastic band.

Abstract: A clamp device is provided for gripping a fabric ply in place in a fabric folding mandrel to prevent slippage of the fabric ply relatively to the mandrel during the folding operation, and means are provided for bodily shifting the mandrel into a position facilitating proper introduction of a fabric ply thereto.

Abstract: A piece of loose textile with a spread cut edge is fed to a stitching location in accordance with a method wherein the piece is gripped at an interior location spaced from the edge and this interior gripped location is advanced continuously at an intermediate transport speed in a transport direction parallel to the edge toward the stitching location. Thus relative to the direction the edge has a leading portion and a trailing portion that are successively displaced past a speed-change location. This leading portion of the edge is advanced in the direction toward the stitching location at a relatively slow transport speed slower than the intermediate speed and the trailing portion of the edge is advanced in the direction toward the stitching location at a relatively fast transport speed faster than the intermediate speed. This system therefore automatically rectifies the edges of the piece.

Abstract: A sewing station in which lengthy material, e.g. sleeve or trouser-leg fabric workpieces, can be provided with a seam in substantially automated operation. The material to be sewn is advanced from a loading station, where it is initially held by a fixed clamp, to the sewing machine. While the material is advanced past the sewing machine by the fabric transport, it is guided by a moving or trailing clamp which trails along with the material holding it in lightly stretched relation to the sewing machine transport mechanism. The clamps are provided with pneumatic pistons which actuate or perform the clamping functions. The pistons are controlled by switches and valves to alternatingly open and close the clamps as required by the seaming operation. The station provides for a simplified operation requiring monitoring by an operator only for the initial positioning and initial seaming.

The guide device comprises a pair of complementary jig devices shaped to fit in juxtaposition with layers of material to be sewn to each other positioned between the jig devices. The jig devices have the same irregular configuration and complementary cross-sectional areas. Clamping devices releasably clamp the jig devices in juxtaposition with the material to be sewn positioned therebetween. Guide members extend from the foot device of the sewing machine for maintaining the guide device in a predetermined position relative to the needle of the machine while the guide device is moved between the foot device and the supporting surface of the feeder of the machine through the entire duration of the guide device.
