FIELD: wood working, machine engineering, instrument making and other industry branches.
SUBSTANCE: installation includes cutting tool and apparatus for mounting and feeding material to be worked. Tool is in the form of working members fed to worked material along pipeline from hopper by means of mechanism for feeding working members pressed to worked material by means of stop and returned to hopper along other pipeline by means of mechanism for returning working members. Said mechanism includes inclined pipeline and pipeline for feeding air provided with additional hopper for worn working members. In description of invention different variants of mechanisms for feeding and returning working members and also different shape and materials of working members are given.
EFFECT: shortened time period for maintaining equipment, enhanced efficiency of working.
