Disclosed is a tire building apparatus and a method for joining or cutting tire components. The tire building apparatus includes a rocking member that is movable in a rocking plane in a rocking motion along a rocking line, a translation guide extending parallel to the rocking line and a carriage that is displaceable along the translation guide, wherein the rocking member has a convex edge that defines a minor arc of a circle and extends up to a rotation center, wherein the rocking member is supported by the carriage at the rotation center and is angularly displaceable with respect to the carriage about a rotation axis extending through the rotation center.

A method for welding two hollow profiled rods made of plastic to form a window frame. The profiled rods to be joined together are heated to a predetermined temperature by inserting a welding plate between their connecting surfaces and pressing the same against the welding plate, forming outer and inner beads, and the profiled rods are pressed together under pressure after removing the welding plate, with a simultaneous increase in the size of the weld bead. For all cross sections of the profiled rods and the plastics used for manufacturing the window frames, to obtain a type of shadow groove on the top side and/or front side and on the bottom side and/or rear side of the finished window frame in the area of or near the connecting sites of the finished window frame, only the outer beads formed on the visible surface of the subsequent window frame in the area of or near the connecting sites of the two profiled rods are pressed slightly inward after removing the welding plate forming an oblique edge, and then are removed together with the inner beads, and then the connecting surfaces of the two profiled rods are joined together.

At least two profiled parts (1) are fixed to profile supports (2) that can be moved relative to each other. The profiled parts (1) are each partially melted at an end joining face (10) with a heating element (5) in a melting step and, after the heating element (5) has been removed, the partially melted joining faces (10) of the profiled parts are pressed against each other in a joining step, until the molten materials brought into contact with each other there cool down and solidify, forming a welded connection. To avoid or reduce occurrence or development of a welding bead, in a separating step that is carried out before the joining step, a mating tool (6, 29) is guided through the melt along the separating edge (9) of the limiting element (3), in order to separate the excess melt (7) that has escaped over the separating edge (9).

The invention relates to a method of fabricating acetate eyeglass frame fronts with a frame curvature and consequent lens seats, which is customized to conform with the curvature of the lenses to be fitted into said seats which, according to the visual defect to be corrected, may have different, possibly asymmetric, curvatures.

The invention also relates to the frames with curved fronts obtained with the method.

Fabrication is carried out by electronically controlled milling operations from an acetate plate (1), having predetermined thickness (S), length (L) and height (H) values, on which additional elements (2, 3, 4, 5) made of the same material, possibly of different colors, are applied, which are attached at least proximate to the end sides of the length extent (L) of the plate at the lens seats. Such additional elements help to locally increase the thickness (S) of the plate to a value (S1) that accommodates the dimensions that the frame shall have as a result of the curvature of the front at the lens seats, relative to the middle region, once the milling operations have been completed.

The additional elements (2, 3, 4, and 5) are pre-cut and then stably fixed to the plate (1) by direct friction welding on the plate, without using chemicals or adhesives.
