Patent number: 4408731Abstract: With the creel for a spinning machine according to the invention at least two rows of rotatably suspended roving bobbins, which extend essentially in parallelism with respect to one another, are adjacently lined-up. Normally in ring spinning machines there are employed for such creels roving deflecting rods which extend horizontally in the longitudinal direction of the ring spinning machine. The rovings extending from the roving bobbins to the drafting arrangements are guided around the deflecting rods for the purpose of guiding the rovings. If the deflecting rod is located behind the bobbins, then insertion of the rovings about the rods is extremely cumbersome, and additionally, there exists the danger of damaging the rovings. If the deflecting rod is located further towards the front, then exchange of the bobbins becomes tedious. These drawbacks are eliminated with the invention in that a row of substantially rod-shaped holders is arranged behind the front row of roving bobbins.Type: GrantFiled: June 14, 1982Date of Patent: October 11, 1983Assignee: Rieter Machine Works LimitedInventor: Eduard Schenkel

The device comprises a ball bearing having an inside race with tangential entrance and exit guides to the race adjacent to opposite axial ends of the bearing. A hub member has an outside diameter less than the inside diameter of the race so that the hub member can be coaxially received in the race and a welding wire passed through the entrance guide and wrapped around the hub and out the exit guide. By now side-loading or expanding the hub against the inside of the race and driving the hub rotationally, the welding wire is continuously fed out the exit guide. The coaxial relationship of the hub and race provides for a very compact structure thereby permitting mounting of the wire feed directly on a welding head carriage adjacent to a weld head or even permitting the feed wire itself to be used as an electrode in a MIG welding system.Type: GrantFiled: February 17, 1981Date of Patent: August 17, 1982Assignee: Dimetrics, Inc.Inventors: Howard D. Lesher, James T. Taff

Patent number: 4322041Abstract: An apparatus and method for winding a multistrand roving package by guiding a plurality of strands along convergent paths of travel towards a winding mandrel employ a pair of spaced strand guide members in the vicinity of the mandrel. The guide members define a gap for the strands and are reciprocated parallel to the mandrel axis so as to alternately engage and deflect the strands into a side-by-side relationship in the package. The strand guide members each have strand guide edge portions so located that, transversely of the mandrel axis, they are offset towards the mandrel from a linearly disposed relationship to intersect the strand paths at different respective angles corresponding to the differences in direction of the strand paths, thereby to compensate for differences in the strand deflections resulting from the differences in direction of the strand paths and to improve the strand deposition.Type: GrantFiled: January 22, 1980Date of Patent: March 30, 1982Assignee: Fiberglas Canada Inc.Inventors: Marius C. Schuller, Leslie J. Harris

Patent number: 4276687Abstract: Capillary fiber bundles of semipermeable membrane material may be used by winding the fibers onto a reel member to form an annular assembly of the fibers, and thereafter cutting the annular assembly into separate bundles. In accordance with this invention, the capillary tubing is fed to the reel through guide slot means elongated in a direction generally parallel to the axis of rotation of the reel. The tension on the capillary tubing is sufficiently low to allow the capillary tubing to move about while winding in the guide slot means in generally random manner. Accordingly, the bundles comprise strands in generally non-parallel, crossing arrangement with adjacent strands. Individual bundles may be wrapped in a special flexible sheet, and cut at their ends for improved quality.Type: GrantFiled: May 21, 1979Date of Patent: July 7, 1981Assignee: Baxter Travenol Laboratories, Inc.Inventor: William J.
