Abstract

Improvements in polishing machines for wooden parts profiled with several propulsion spindles of workpieces propelled in the same direction, supported parallel to each other and with respect to the axis of rotation of the switching star on the periphery of a switching star capable of rotating stepwise, and with two abrasive canvas supports arranged side by side in the peripheral direction of the switching star, capable of being propelled oscillating at an almost straight angle with respect to the longitudinal direction of their hanging abrasive canvas strips downwards, which supports have a plurality of polishing stations which are arranged side by side in the peripheral direction of the switching star and are formed by the support bodies which compress the abrasive canvas strips elastically against one of the work pieces.
