DEVICE OF CHANGE SHAPE OF SEAM Russian patent published in 2012 - IPC D05B3/02 

FIELD: textile, paper.

SUBSTANCE: device of change the shape of seam contains a shaft mounted in bearings of the housing, bearing a block of feeler units which includes a feeler unit of an automatic software of displacement of tissue feed in contact with a stripper, mounted with the possibility of oscillating in the mode of stitch execution of complex zigzag with software combined control by mechanisms of needle and the feed of tissue kinematically connected with the control handle of the tissue feed, mounted on the axis, and a cam of smooth adjustment of the stitch length. According to the invention it is provided with a transitional feeler unit for transfer the stripper from the feeler unit of automatic software of the tissue feed displacement by a cam of smooth adjustment of the stitch length, made in one piece with the said feeler unit with a narrow lateral cylindrical surface and conical surfaces, by which it is coupled with its cavities and protrusions. At that the narrow lateral cylindrical surface is made with a diameter equal to at least half the sum of the diameters of protrusions and cavities of the feeler unit of the automatic software and is located on the same level with the cam of smooth adjustment of the stitch length, which with the stripper has the ability to contact in the mode of performance of straight and zigzag stitches with control of the needle mechanism.

EFFECT: simplified design and manufacturability of the design features.
