  • Patent number: 5383418
    Abstract: A synchronized, indexed positive material top feeding system for use with sewing and other applications. For example, material being fed to and through the sewing area of a sewing machine, is constantly "gripped" at the top thereof in front of, behind and in the sewing area as well as through an adjustable presser bar. This process takes place without affecting machine speeds, and in feeding movement that is synchronized with the machine feed dog for similar or variable stitch travel. This process is facilitated by a belt with "teeth" that contact and provide frictional engagement of the top of the material.
    Type: Grant

  • Patent number: 4527491
    Abstract: The present invention teaches a system which, utilizing pneumatic logic, folds and positions pre-cut belt loop material for joinder to pants. The pre-cut material is loaded while joinder is occuring. Two pairs of upstanding pins supported by fingers receive individually cut belt loop fabric pieces which can be made from scrap to match colors and, in a preferred embodiment of this invention, two tacks secure the loop to pants in the case of jeans. A novel adjustable cam control arrangement and means for rotating the fingers is described in the following specification. In a second embodiment, one visible and one invisible tack can be made securing the belt loop to the pants, with the visible and invisible tacks being placed either top and bottom or bottom and top, respectively, as selected.

  • Patent number: 4476760
    Abstract: A fluid actuated cutting machine comprising a stationary lower blade and a vertically movable upper blade mounted at one end to a pivot rod. The upper blade is disposed at angle relative to the horizontal plane. The other free end of the upper blade is disposed beyond a vertical plane on which lies the cutting edge of the lower blade. A pressure arm, mounted on a cantilivered beam connected to the base of the machine, acts against any tendency for the upper blade to align its cutting edge with the cutting edge of the lower blade. During its downward movement, the upper blade is constantly drawn from its horizontally angled position relative to the lower blade towards alignment with the lower blade. This movement is resisted by the pressure arm. The resistance causes a firm cutting pressure between the two blades at the constantly moving contact point during the downward movement of the upper blade.

  • Patent number: 4462530
    Abstract: The present invention teaches a high-speed indexing system for use with any number of fabric-moving apparatus, a novel braking system for use within the indexing system, and a novel puller accessory. The high-speed adjustable indexing system is illustrated in connection with a sewing machine, as an example. In sewing machine applications, a synchronized intermittent advancement of fabric in unison with the movement of an associated feed dog is provided. Undesirable inertia-caused roller overshooting, heretofore treated with anti-reverse clutches and other approaches, is eliminated, thereby enabling high speed indexing at machine operating speeds conventionally unattainable in the art. An adjustable spring-biased braking arrangement is provided which may be preset for known machine operating speeds.
