Title: Improvements in or relating to a method and apparatus for the manufacture of rubber thread
IPC: B29D99/00
Filed: 1933-07-05
Abstract: 404,219. Rubber threads. INTERNATIONAL LATEX PROCESSES, Ltd., 10, Lefebvre Street, St. Peter's Port, Guernsey.- (Assignees of Gammeter, J. R.; 680, North Portage Path, Akron, Ohio, U.S.A.) July 5, 1933, No. 19051. Convention date, Aug. 6, 1932. [Class 70.] Rubber thread is made by depositing rubber from a rubber containing fluid preferably latex on to a continuously progressing surface having a series of grooves therein in the direction of travel of the surface and wherein the grooves are separated by comparatively sharp edges so as initially to produce in the grooves a series of continuous rubber threads connected by relatively thin films of rubber over the sharp edges between the grooves. These thin films are subsequently cut by pressure against the sharp edges. In operation rubber latex from the container 10 is spread on the travelling band 13 by the spreader 14, passed through the oven 17 and then between the rollers 20 and 21. If compounding ingredients were included in the original latex vulcanization takes place in the oven 17, and the material emerges as a series of rubber threads joined together by a thin skin of rubber which is cut by the sharp edges of the grooves during the passage between rollers 20 and 21. If desired a separate vulcanizing chamber may follow the drying chamber 17. The threads now pass between the take off rolls 22 and 23 and on to the winding up spools 24. The air in 17 is heated by passage through the blower 18 and heater 19. The roller 21 may be heated if desired. The band 13 which is preferably made of stainless steel is cleaned on each circuit by the buffer 16.

Abstract: 933,987. Folding fabrics. DOVE ENGINEERING Ltd. May 22, 1962 [May 30, 1961], No. 19546/61. Class 42 (2). A machine for laying a web of fabric 15 in zig-zag formation on a table 12 comprises a carrier reciprocable along the table 12 and having a guide 13 slidably mounted at each side thereof on a vertical shaft 14; two spaced guide members 18, 19 slidably mounted on the guide 13 to normally rest in close proximity to the table 12, the member 18 guiding the fabric 15 during traverse of the carrier to the right of Fig. 1 and the member 19 guiding the fabric during traverse to the left; and a gripper 23 mounted at each end of the table to slide vertically and having a surface to co-operate with a surface of the guide 13 so that when the carrier reaches its end position the guide 13 raises the gripper 23 which lifts the adjacent inoperative member 19, say, so that the gripper 23 is above the operative member 18 whereupon the gripper 23 disengages from the guide 13 and falls to grip the formed end fold of the fabric and to permit the carrier to return. In operation, as the carrier approaches the right-hand end of travel an inclined plate 24 on the carrier engages a roller 25 on the gripper bracket 20 which thus rises vertically. The bracket 20 raises the member 19 relative to the guide 13 by engagement with an abutment 26. On further movement of the carrier the gripper 23 deflects the part of the fabric 15 between a guide 16 and the member 18. The roller 25 clears the plate 24 so that the bracket 20 falls and the gripper 23 falls on to a surface 27 of the member 18. The carrier movement is reversed and the member 18 withdraws leaving the gripper 23 clamping a fabric fold. During the return movement of the carrier the roller 25 engages the underside of the plate 24 which is restrained against anticlockwise movement to cause the guide 13 to be raised on the shaft 14 by a predetermined amount and the member 19 falls to its rest position. To facilitate adjustment the roller 25 may be mounted on an eccentric spindle.
