Abstract
In order to obtain a simple, inexpensive and low-maintenance monitoring device for controlling the setting width of individual teeth of saw blades or belt-saw blades, in particular for controlling the setting result of a setting machine the present invention invisages that the monitoring device comprises at least one photo-detector whose light beam at least partly runs through one or both regions laterally next to the running-past saw blade or belt-saw blade, into said regions the set teeth project.
Claims18
A monitoring device for controlling a setting width of individual teeth of longitudinally moving saw blades or belt-saw blades, comprising:
- at least one photo sensor positioned at an angle with respect to a center plane of the moving saw blade or belt-saw blade, having a light emitter and a light receiver that are directly opposite each other;
- wherein said light emitter emits a light beam at least partly through a monitored region, that is laterally adjacent to the moving saw blade or belt-saw blade, where a set tooth projects laterally from said saw blade or belt-saw blade;
- and
- said light receiver detects said light beam after it passes said monitored region.
