Abstract: This method of making packets of amorphous metal strip adapted to be wrapped about the arbor of a transformer-core-making machine comprises providing first and second composite strips, each comprising many thin layers of amorphous metal strip stacked in superposed relationship.      The composite strips have leading ends that are located in initial positions (i) axially spaced from each other at the start of a packet-making operation and (ii) at opposite ends of a stacking zone where the packets are built up during a packet-making operation. The composite strips are cut to detach first sections of strip from the first composite strip and to detach second sections of strip from the second composite strip; and the detached sections are axially advanced forwardly of the respective composite strips from which they are detached into said stacking zone. The second sections are stacked in alternating relationship upon the first sections in the stacking zone.      We utilize for advancing each of the first sections into the stacking zone first transport means that is moved in a first-strip forward direction during said advancing of each of the first sections and is returned to a home position in preparation for each succeeding advancing operation of a first section. For advancing each of the second sections into the stacking zone, we utilize second transport means that is moved in a second-strip forward direction during said advancing of each of the second sections and is returned to its own home position in preparation for each succeeding advancing operation of a second section.      Each of the second-section advancing operations is performed concurrently with return motion of the first transport means toward its home position, and each of the first-section advancing operations is performed concurrently with return motion of the second transport means toward its home position.

Title: Apparatus for centering a wheel on a hub
Inventor: ROGERS LARRY KEITH
IPC: B60B3/16
Filed: 1994-01-26
Granted: 1998-12-22
Abstract: A centering apparatus for centering a detachable vehicular wheel with a central opening on a hub. The one-piece centering apparatus fits in an annular groove in the hub pilot boss. The one-piece centering apparatus may be in the shape of a ring, with bendable and resilient fingers extending outwardly from the ring at an angle away from the outer end of the pilot boss. As the wheel is mounted over the hub pilot boss, a flange at the wheel central opening presses against the fingers on the ring. This causes the fingers to bend slightly to compensate for any interference fit. The resilient action of the fingers keeps the wheel centered on the hub. The wheel is then bolted to the wheel assembly. In other embodiments, the centering apparatus has a cross-section in the approximate shape of a "V", "U", "N", or "M", one leg of which serves as the bendable and resilient finger. The fingers may be replaced by a continuous member extending around the circumference of the pilot boss. The centering apparatus may also be a coiled wire in the shape of a toroid. The centering apparatus alternatively can be retained in an annular groove in the margin of the wheel central opening, with the bendable resilient fingers extending inwardly to press fit with the hub pilot boss and center the wheel on the hub. Various materials may be used for the centering apparatus.
