Method and device bub trimming the side edges in particular clay conveyor belt blanks

The invention relates to processes suit the creaming of the Side edges of band-shaped »soles made of unTulk & nisier ·» te »rubber or similar plastic materials, in particular Clay conveyor belt blanks »which then» wipe the outflowing ones Orphans guided by a calender or rolling mill as well as on facilities «to carry out such procedures.

They manufacture, for example, clay conveyor belt «*! As a precautionary area of use for the invention, the need for the ready-made belt blank from continuously or section-wise snapped, in subsequent work plaetiao-high material webs pressed against one another under the effect of pressure, the need for the pre-cut blank is not cut on both side edges Width is reduced to the size seen by the gate »but also to compensate for the unavoidable inaccuracy when the tracks are closed, with a smooth» straight edge «. The cutting knives are arranged in the cone immediately in front of the calender, which is used to press the cut-out webs, from which, in a logical sequence of the manufacturing steps, resulted in the generally customary process of guiding the trimmed blank together with the edge strips through the orphans of the calender and only after the roller has passed through the rollers, separate the running pandat tires from the hollow and apply them separately.
