Title: Process for the formation of single and/or multi-row two-thread stitch lines of one-thread chain stitches, intertwined with an additional thread and device for its implementation on sewing machines
Inventor: SILOCI HARALAMPIE
IPC: D05B1/02
Filed: 2011-03-24
Abstract: The invention relates to the clothing industry and can be used for the formation of two-thread stitch lines in garments, for sewing of different cloths, including nonwoven, pile and agricultural cloths.The process for the formation of single and/or multi-row two-thread stitch lines of one-thread chain stitches, intertwined with an additional thread, consists in that before each entry into the cloth of the needle, threaded in with a main thread, on the needle is wound an additional thread with a full turn/half-turn around the forefront of the needle tip, and after withdrawal of the needle from the cloth the main and additional threads are tightened by the movement of cloth and the thread tensioner.The device for the formation of single and/or multi-row two-thread stitch lines of one-thread chain stitches, intertwined with an additional thread on a sewing machine, contains a main shaft connected to an electric motor, a needle bar with needles, threaded in with a main thread, loopers with loop holders, fixed on a lower shaft, a clamping foot, above which is fixed a guide plate with bushes for loops, and a winding mechanism, on which are fixed bosses with an additional thread with the possibility of rotational motion around the bushes for loops.The device, during the work of the sewing machine with thick, tough, non-woven and agricultural cloths, contains over the loopers a plate, into which is made a main hole and guide grooves to prevent the unwinding of threads around the needle at cloth thickness differences. The device, during the work of the sewing machine with pre-clamped in the clamps-forms cloth, is additionally equipped with a cloth advancement device.

Abstract: The securing and arming device has an operating body and a delay element one inside the other, so that they constitute outer and inner wheels without a wheel shaft. The wheels have parallel geometric wheel axes and define a ring-like gap between them. At least one of the wheels is embodied to be wavy on its surface facing the other wheel, with wave crest and troughs over its circumference. <??>The securing and arming device comprises an operating body (20) which, prior to an arming time, is secured in its position of rest on a support device (12) by a securing element (30) which is in a securing position; can, for the purpose of arming, be released by the securing element which is moved into its release position in relation to the support device; and can, after the arming time, be brought into an operating position by a rotary movement around a trigger axis. The device has a delay element (22) which can be driven in the course of the rotational movement of the operating body and to delay the rotational movement of the operating body. The operating body and the delay element are arranged one inside the other, so that they constitute outer and inner wheels without a wheel shaft. The wheels have parallel geometric wheel axes and define a ring-like gap between them. At least one of the wheels has a wavy surface facing the other wheel, with wave crest and troughs over its circumference. With areas of the wheel surfaces facing each other, the wheels rest against motion transfer bodies (24) in the ring-like gap and which are seated radially displaceable in the solid gap. <??>An Independent claim is also included for a spin-stabilized projectile comprising a casing defining a rotating part of the projectile and the longitudinal axis of the projectile about which the projectile is spin-stabilized; and a securing and arming device.
