ABSTRACT:
The apparatus forms a profilated collimator strip out of a band of deformable material. It contains a first and a second forming tool, both of which contain a row of forming teeth. The teeth may be hexagonal to form corresponding deformations having sidewalls greater in width than the top or bottom walls. In operation, the teeth are disposed oppositely and staggered with respect to each other. The apparatus also contains a device for performing a relative movement between the two tools, whereby the tools approach each other. The apparatus also includes a device for moving one of the tools parallel to the other one in an indexing step by step motion. In the method for forming a profilated collimator strip, a band is placed on one tool, whereby a portion of the band is located in the space between the two tools which are positioned oppositely to each other. Then the tools are approached to each other, the teeth thereby pressing the band into the predetermined shape. When the tools are subsequently retracted from each other, one tool is moved in a step motion parallel to the other tool. Thereby, an additional portion of the band is introduced into the space to be formed.
