Abstract: (EN) The aim of the invention is to create a pair of men's boxer shorts (10), which are provided with a front part (11) and a rear part and with a band (14) running along the front pail and rear part, in which a certain support during wearing is made possible in the form of a type of athletic support. To this end, the inside of the front part (11) is provided with an insert part (30), which extends on both sides of its longitudinal center and which has a free edge (36, 37) each facing away from the longitudinal center. In addition, both free edges (36, 37) are united in or near the crotch area (17) while forming a trough-like area (39) by the lower area of the insert part (30).

Abstract: Profiles or sectional shapes formed of elastic masses, especially rubber, are equipped with velour bands or tapes. The application of the velour bands is accomplished in the already formed profile which is still in a heated state, by slightly pressing the band carrier into the mass. The apparatus utilizes a guide element operatively associated with an injection disk or nozzle of an extruder, in order to deposit the velour band into the material at the extruder outlet. The profiles thus formed are used as sealing profiles in the window guides in the automotive industry.

Abstract: A method of, and apparatus for, automatically and uniformly drawing-in elastomeric material into worm extruders comprising at least one draw-in roll for the material mixture, arranged in spaced relationship in front of the extruder worm or screw and driven independently of the worm. The draw-in roll is driven in a manner such that it only can transmit a predetermined adjustable rotational moment which is limited towards an upper range, or, if desired, the rotational speed of the draw-in roll is controlled as a function of a maximum upwardly limited pressure prevailing within a draw-in or infeed pocket between the draw-in roll and the worm or screw.

Abstract: A change device for sieves used for filtering plastic materials. The change device comprises a sieve holder having a bore for the throughflowing material and a slot extending transversely thereto, in which there are sealingly retained in work position sieve supports or carriers containing sieves. By means of a work cylinder it is possible, without interrupting the transport of the material which is being processed, to eject and replace the contaminated sieve by a new sieve. The rapid change device is particularly suitable for installation in an extruder for fabricating rubber hoses for automobile tires, the installation of such rapid change device advantageously being accomplished between the extruder and the injection head.

Abstract: A strip cutter apparatus for rolled sheet formed of rubber and elastomeric materials, comprising a transport device for the rolled sheet and a plurality of disc-shaped cutters arranged transversely with respect to the transport direction of the material. The cutters cut the rolled sheet into individual strips. A revolving brush is driven in the direction of transport and is provided after the cutters, viewed in the direction of travel of the rolled sheet. This revolving brush is arranged in such a manner that its bristles penetrate into the intermediate spaces between the cutters and displace away from the sides of the cutters any material which possibly has been raised by the cutters.

Abstract: Method for treating bands of heated non-vulcanized rubber for handling upon removal from a rolling mill which includes the formation of a web of material, and the severing of the web along lines parallel to the web axis to form processing strips. The web is initially formed having a width substantially equal to an integral multiple of process strips, and thereafter the web is partially slit longitudinally along a substantial portion only of the length to provide a plurality of strips, each of the strips being coupled together across a transverse header arranged integral with each of the strips for facilitating handling. The technique is particularly adapted for treatment of the heated non-vulcanized rubber prior to the passing of the material through a cooling tunnel preparatory to storage.

Abstract: A mold for fabricating articles formed of a fluent material, especially rubber, comprising at least two mold parts enclosing a mold compartment. One of the mold parts possessing a tear or break groove at the region of the mold parting plane, the tear groove surrounding the mold compartment. The tear groove provided in said one mold part has an inner wall which is located exactly opposite the marginal or outer rim of the mold compartment formed in the other mold part and encloses an angle of about 90.degree. or less with the mold parting plane.
