Abstract (en)
[origin: WO2021074681A1] The invention relates to a device comprising laterally mobile pressure devices (16) on belt grinding machines in continuous operation. These pressure devices are positioned in such a way that workpieces (11) detected by detectors (14) are ground in a laterally limited area in the longitudinal direction. An arrangement of such pressure arrangements constitutes a segmented grinding pad, for example. The invention also relates to the method for laterally moving the segments (13) thereof and to the devices created for this purpose. These methods and devices enable, among other things, frames to be ground in the wood grain direction of their friezes and/or their internal fillings or also grinding patterns to be applied to workpiece surfaces.
