Patent number: 4411207Abstract: A yarn saving apparatus for conventional tufting machines which includes means for sensing the lateral movement of a needle bar or other laterally shiftable patterning device, and means responsive to the lateral movement of the needlebar or other lateral shifting device for slowing the speed at which yarn is fed to the outermost groups of needles of the needle bar, thereby withdrawing yarn from loops formed thereby, so as to prevent wastage of the yarn which would otherwise be tufted into a wastage area at the outer longitudinal border of the carpet backing. Yarn is provided to the groups of tufting needles at the normal rate when the tufting needles are positioned over an area which is to be tufted, and yarn is provided to the groups of tufting needles at a slower rate which effectively withdraws yarn from loops in the wastage area when the groups of needles are positioned over the wastage area.Type: GrantFiled: April 22, 1982Date of Patent: October 25, 1983Assignee: Tuftec, Inc.Inventors: James D. Brock, Gerald B. Morrison

Patent number: 4222498Abstract: Apparatus for measuring out material from a cold feed bin for use with a drum mix plant. The apparatus comprises a plurality of cold feed bins supported on a plurality of legs above a frame. Each leg of the bins rests upon a load cell which thereby measure the weight of the bin and material contained therein. Control circuitry connected to the load cells regulates belt feeders disposed below each bin which adjust the rate at which material is dispensed from each bin in response to the weight measured by the load cells to maintain a desired rate of weight reduction. A belt conveyor disposed below the belt feeders transports the dispensed material to the input of a mixing plant.Type: GrantFiled: January 17, 1979Date of Patent: September 16, 1980Assignee: Astec Industries, Inc.Inventor: James D.
