Abstract: This is a needle bar handling system for a sewing machine. More specifically, it is a handling system that allows the length of the needle bar stroke to be varied according to the thickness of the fabric to be sewn.
Abstract: Positioning device adapted to dispose a strip of fabric or other similar material on an article of clothing do as to form a loop, the strips divided into a central portion and two opposite ends, the positioning device rotates at least one of the two ends of the strip in order to bring that end or ends into abutment with the central portion of the strip; and wherein guide means guide the end or ends of the strip during rotation.
Abstract: Conveying device to be mounted on a sewing machine comprising a plate to be constrained to a base of the sewing machine, a conveyor belt mounted on two rollers constrained to a supporting structure so as to rotate, the supporting structure being coupled with the sewing machine, so that the conveyor belt is adjacent to the plate, and motor means connected with the conveyor belt and suited to put said belt in motion so that a cloth arranged between the plate and the conveyor belt translates when the conveyor belt is put in motion. The conveying device comprises at least a pressing element actuated by a piston of a cylinder which comprises elastic means and is constrained to the supporting structure of the conveyor belt, said cylinder being connected with a pressure control system. The pressure control system adjusts the pressure acting on the cloth to be conveyed since the elastic means are adjustable through the same system and the pressing element is in contact with the portion of the plate and/or belt.
Abstract: A machine for forming and ironing folds in cloth has a plate frame on which are fixed a support and pressure system, a template on which the cloth is put, a moving system for moving a blocking plate which blocks the cloth, a guide system for guiding a folding element which folds outer edges of the cloth and an ironing plate. The guide system has a guide profile and a translating arm which is translated in a longitudinal direction and has a roller and a folding element. The arm is under pressure towards the guide profile so that the roller beats and slides along the edge of the guide profile. In this way, the folding element follows the movement of the arm according to the guide profile and moves in the longitudinal direction and a transversal direction.
Abstract: Sewing machine (10 comprising a base (12) with a crochet and a head (14) that comprises a needle support (30), a fabric pressure foot (24) and its adjusting means (26), motor means (28) to make a needle sew together with the crochet, and lever means (32) to turn the rotary motion of the driving means into a vertical reciprocating motion. The needle support (30) in turn comprises at least two needle bars (46, 48) that are moved vertically by said lever means (32), and a connecting element (50) to couple the lever means (32) with at least a needle bar (46,48). Each needle bar (46,48) is coupled with a needle (16,18) through a respective thread and actuated selectively in the crochet in order to allow the sewing.
