Abstract: A method for making weather strips in which a polyurethane film is positioned along an anvil having longitudinal parallel spaced anvil surfaces and recesses therebetween with elongate channel-like portions of the film in the recesses. Resiliently compressible polyurethane foam is pressed against the polyurethane film along the anvil so that the foam is compressed against the anvil surfaces and extends into the channel-like portions of the film in the recesses. The compressed foam and film along the spaced anvil surfaces are then sonically welded to fuse the foam together in its compressed state and fuse the compressed foam to the film, and the fused foam and film are slit along the anvil surfaces to form separate weather strips.

Abstract: This machine is intended for bonding stretched pieces of elastic band to a moving sheet so that these pieces extend transversely relative to the direction of movement of this sheet.The pieces are transferred from a cutting station to a stretching station by means of a transfer station.The stretching station comprises several pairs of grippers distributed around an axis about which they are driven in rotation. The grippers of one and the same pair are arranged axially opposite one another and are designed to be successively moved away from, and close to, one another so that, during their rotation, they grip the lateral ends of the pieces subsequently stretching the latter by moving axially away from one another. Once stretched, the pieces are bonded to the sheet entrained about a drum at the moment when the grippers pass opposite this sheet.The invention is used for the production of a composite sheet intended for providing diapers.

Abstract: A vehicle wheel has a pneumatic tire mounted thereon. The wheel has a rigid rim having essentially radially inwardly extending rim flanges and, on the radially inner side of the rim ring, the rim has respective mounting spaces, each with a deep mounting bed. The pneumatic tire is provided with tire beads having a cross-sectional form which, on the one hand, permits the tire bead to extend into the mounting space and deep bed during mounting, in which, on the other hand, closes-off the mounting space and deep bed when the tire is in its operational state. In order to disconnect the tire seat from the rim support surfaces, it is proposed that the deep mounting bed extend directly to the rim flange, and that, in the operational state of the tire, on the one hand the tire bead be spaced from that portion of the rim ring that is adjacent to the rim flange, and on the other hand a portion of the tire bead butt axially inwardly against a portion of the rim.

Abstract: A vehicle wheel end assembly (10) is adaptable for use with an on-board central tire inflation system. The assembly provides a passage for the routing of air between the on-board system and the vehicle tire. The assembly comprises a stationary spindle (12) and a rotational hub (14) mounted thereon. The hub is supported for rotation by first and second axially spaced bearing sets (16, 18), each having an inner race (20, 26) and an outer race (22, 28) associated with the spindle and hub, respectively. The inner race of the inboard bearing set (18) is formed with an axial air pressure (46) which communicates with an internal chamber (36) in the hub to form a portion of the air passage between the tire and on-board system. In another feature, rotary seals (60, 62) are seated in opposed faces of the bearing sets and include sealing lips (72) which have a sealed contact with the upper surface of the inner bearing races.

Abstract: A apparatus is described for producing optically satisfactorily laterally spaced letters which have been sequentially transferred from a dry transfer sheet. The sheet (28) is held in a holder (20) which incorporates a short free-motion linkage enabling the sheet so held to be moved horizontally over a short distance, the short distance being accurately repeated each time such movement is effected. By butting the letter next to be transferred to the letter just transferred and then moving the fixed distance away, visually pleasing letter spacing may be simply achieved without the use of extra transferable markings which need to be transferred to the working surface and subsequently removed, and without the need for excessively complex apparatus or for drawing alignment or spacing lines on the receptor.
