Patent number: 4010664Abstract: Ply stock is delivered to a bias-cutter by a feed mechanism which moves the stock to be bias cut in measured increments of length. The present apparatus provides a smooth continuous surface of a feed pan supporting the full width of the ply stock to a forward edge which is adjustable angularly to the angle of the desired bias cut. The feed pan moves toward the shear line of the bias-cutter with the ply stock held on the surface; then with holding clamps released is drawn away from the shear line while the ply stock is held to the shear line. The feed pan is less subject to distortion or deflection and is relatively insensitive to changes in humidity. Accuracy of both bias angle cut and length of cut are improved.Type: GrantFiled: March 19, 1976Date of Patent: March 8, 1977Assignee: The Goodyear Tire & Rubber CompanyInventor: Richard P. Marshall

Patent number: 4008637Abstract: This disclosure teaches an apparatus for manufacturing and stacking hemmed fabric pieces (usually pockets) with the hems either lined or unlined. In the case of lined hemmed fabric pieces, pieces of a liner tape are fed in cut lengths in turn along a path. Limp fabric pieces (the pockets) are inserted manually by an operator and are positioned automatically each on one of the liner pieces. A hem is formed out of a margin of the fabric piece around its related liner piece and a terminal margin flap is tucked under itself. The hem is sewn along the terminal flap. The hemmed lined fabric pieces are then inserted in turn into a cartridge upwardly and the cartridge is revolved about a vertical axis as successive of the hemmed lined fabric pieces are inserted therein so that uneven height caused by the hems is distributed about the stack. In the case of unlined fabric pieces, the apparatus functions substantially the same in positioning the limp fabric pieces, hemming and stacking.Type: GrantFiled: April 23, 1975Date of Patent: February 22, 1977Assignee: Cluett, Peabody & Co., Inc.Inventors: Douglas J. Crawford, Roger LeMere, Francis H. Hughes

Patent number: 4003278Abstract: A device for cutting lengths of tubing from a longer tube utilizes an external pair of cutting dies and an internal pair of punches. An eccentric relative motion ("shimmy") of the cutting dies results in the desired cutting of the tube. The punches are inserted into the tube from the end of the tube from which the length of tubing is to be cut. A restraining arrangement prevents the punches from moving farther along the tube than is desired, while a punch positioning mechanism prevents movement of the punches toward the open end of the tube. Thus, the internal punches are accurately positioned with respect to the external cutting dies. A centering arrangement is utilized to insure coaxiality of the punches.Type: GrantFiled: March 14, 1975Date of Patent: January 18, 1977Assignee: Jackes-Evans Manufacturing CompanyInventor: John Tipton Shields
