ABSTRACT:
The subject matter of the application is based on a process for the manufacture of screen components of various lengths for system screening decks, the screen components having substantially the form of a plate or at least a frame with longitudinal and transverse members. The screen components consist of a weldable plastic and are subdivided into short components with a square and/or rectangular basic shape and into long components two or three times the length of this basic shape. The screen components have in each case, on supporting members arranged on both longitudinal sides, fastening elements, which project from the undersides, or edge fastening recesses spaced in a certain pitch independently of their lengths. In spite of their various lengths, such screen components are to be manufactured in injection-moulded quality, for which only one injection mould in a single format corresponding to the basic shape is necessary. For this, the screen components are first produced as blanks in the basic shape, with an allowance on their sides running transverse to the support, and, from the blanks, the short components are manufactured by cutting off the allowance and the long components are manufactured by butt welding at the transverse sides and melting off the allowance.
