  • Patent number: 5038692
    Abstract: Wheel low fabric feeding for sewing machines where oscillations of the feeding shaft are transmitted to two gear couples mounted on free release wheels fixed to a support pivoted free to rotate. By acting on a stitch length regulator device one of these couples engages the feeding wheel for reversing the rotation direction of the wheel and thus the work feeding direction.

  • Patent number: 4917030
    Abstract: A machine which draws one by one a certain number of fabric layers, overlaps them and sews them in a completely automatic way, and which is composed of a stripping unit which draws the single fabric layers and disposes of them on a plane, a television camera and an electronic elaborator which determines the position of the fabric layers on the plane, a driving unit which, according to the determined position, draws and overlaps the fabric layers by means of an assembling device, and a sewing unit which receives the overlapped fabric layers from the assembling device and sews them together.

  • Patent number: 4905616
    Abstract: An assembling device for fabric layers of simple construction providing two plates connected to each other, one of which carries a plurality of needles and the other of which has a series of corresponding holes. The two plates may be brought near to each other, so that the needles jut out from the holes for transfixing the fabric layers, and may be removed so that the plate with the holes slips off the fabric layers from the needles. A locking mechanism is provided with locks, in an unlockable way, the two plates in their approached position.

  • Patent number: 4765268
    Abstract: Automatic device for detaching the cam followers in a sewing machine where a selector knob, when it is rotated, provides the detachment of the cam followers in the first portion of rotation, and positions the desired cam in correspondence of the cam follower in the second portion of rotation. On the reduction collar of the selector knob two opposite grooves are made out, which engage pins transmitting the translation movement to a shaft which operates a cam follower detaching lever.

  • Patent number: 4719863
    Abstract: A small cloth vise in a sewing machine arranged for the automatic application of small pockets applied on blue-jeans or on other similar garments by two fixing seams where at least on one side the seams are not parallel, comprising a central element, a cylinder fixed to the element, a small plate which transmits motion driven by the cylinder, a first blade placed under the central element for displacement in proximity to the seams operatively connected to the small plate, and first and second levers having ends connected to the blade corresponding to the side where the seams are not parallel, the first lever effecting a displacement larger than that of the second lever for causing the blade to rotate and thus to translate in sequence.

  • Patent number: 4712494
    Abstract: Automatic exchange of the size in an automatic sewing unit which comprises a sewing machine displaceable along two axes and a workpiece clamp group formed by at least two half-clamps, one of which is fixed and the other of which is mobile. In order to obtain different desired sizes, the machine, positioned at a basic size .phi. corresponding to the position .phi. of the axis, is automatically displaced in a positive way for reading the displacement made by the mobile half-clamp. The size is obtained as the difference between the trigger coordinate of a proximity fixed to the sewing machine and a memorized fixed coordinate corresponding to the basic size .phi..
