A roller bearing cage for guiding rolling bodies in a rolling body bearing, which has multiple rolling bodies, two cage side elements, between which the rolling bodies are arranged, and which have multiple web appendages to guide the rolling bodies, and multiple connection elements that connect the two cage side elements. The azimuthal position of the connection elements defines a connection area. Exactly one connection element and at least one web appendage are arranged in a connection. The connection element and web appendage are arranged in sections inside a radial interior of the respective cage side elements, the border of which is defined by the positions of the rotation axes of the rolling bodies.

The invention relates to a method and an apparatus for welding thermoplastic molded articles wherein additional simultaneous irradiation, in the welding area (), of one of the join partners () will lead to a temperature increase of this join partner, occasioning process-reliable welding.

Method and device for welding thermoplastic material shaped parts, particularly for contour-welding three-dimensional shaped parts

In a method and an apparatus for irradiation welding of two thermoplastic components, a local temperature maximum, which circulates together with the laser beam and increases from cycle to cycle, and a correspondingly circulating, locally increased clamping pressure are generated in the area of joining.
