Definitions

  • This invention generally relates to procedure and apparatus for sizing and shaping garments. This invention relates more specifically to apparatus and procedure for stretching and re-forming knitted garments, such as sweaters, that have been shrunk as the result of dyeing, washing or other manufacturing treatments.
  • sweaters are often soiled during manufacture and must be washed prior to finishing. Also, unevenly knitted sweaters are treated with chemical sizing compounds that enable them to hold their proper shape. These and other treatments will cause sweaters, and knitted garments in general, to shrink and require re-forming.
  • Sweaters whether malformed or not, require a finishing operation, such as pressing, to remove wrinkles developed during manufacturing processes. Also finishing operations will slightly re-form sweaters to remove small imperfections and unitize or give body to the garment.
  • One preferred means of finishing sweaters involves the use of a pre-shaped, expanding-frame that fits inside an individual sweater. A sweater fitted onto such a frame will be placed under slight wrinkle-freeing tension. By subjecting a sweater under such tension, first to steam and then to dry air, the sweater will be pressed or finished in its final desired configuration without disturbing the natural texture or surface character of the yarn.
  • an expanding-frame garment finisher will stretch a knitted garment slightly, it cannot satisfactorily re-form a sweater that has seriously shrunk as the result of chemical treatment.
  • an object of my invention has been to discover and develop a procedure for uniformly re-sizing and re-shaping malformed garments such as Sweaters;
  • Another object of my invention has been to produce a machine that can be conveniently operated to automatically stretch and re-form sweaters;
  • Another important object of my invention has been to provide a single machine on which a sweater can be loaded for both wrinkle-free finishing and stretch resizing and re-shaping;
  • a further object of my invention has been to provide a sweater re-forming machine that can be easily adapted for use with sweaters of various sizes and shapes, and that can be pre-set for automatic operation on sweaters of the same size and shape;
  • a further important object of my invention has been to provide a sweater re-forming machine that is composed of relatively simple, easy-to-operate and maintain mechanisms;

  • FIGURES 9 and 10 are fragmental frontviews of a portion of my machine illustrating alternative arrangements for attaching the collar finishing attachment of FIGURE 8 to mymachine.
  • One phase of my invention relates to the use of a garment finishing stand or form having. the desiredside and arm contours for shaping the garment. Upper portions of the garment are supported on the finishing stand-while the garment is stretchedby. means that grip its bottom periphery or waist portion.
  • Another phase of my invention relates to the use of pre-set adjustable stretching limits and adjustable-length pneumatic-actuator piston rods whereby the re-forming machine can be pre-set to automatically reproduce a desired stretching operation for garments of ditferent size.
  • Another important phase of my invention relates to the H use of sweater gripping means that are-selectively automatically held in either a grippingor non-gripping po sition to make the most efiicient use of the machine operators hands.
  • a further phase of my invention relates to the use of a collar forming attachment that can be selectively em pl-oyed to stretch and re-form thecollar and upper portions of the sweater or to hold the collar and upper portions of the sweater in a pre-formed position during the stretching operation, or to move and stretch the collar and upper portions of the sweater somewhat less than the stretching movement applied to the garment waist portion.

It will be seen that as the pneumatic actuator 31 causes the toggle links 32 to pivot the side adjuster links 27 outwardly, the side-creaser bars 26 and the arm-forming frame members 22 and 24 will spread or expand.
  • the actuator can be provided with an adjustable stroke limit stop (not shown) that will automatically determine the ultimate degree of frame expansion as required for garments of a given size and material.
