ABSTRACT:
A device is fitted on automatic cycle woodworking machines and is able to protect the material subjected to machining against the danger of it splintering in the region of the outgoing edge of the tool.
The device consists of a movable element provided with a splinter preventing block and constituted by a carriage movable, in two directions, along the infeed path of the pieces to be machined. The carriage has connected to it an extension to which is secured a wood block that constitutes the splinter preventing means for the pieces to be machined, and this is able to rotate around a longitudinal axis along which the carriage traverses from a position away from the piece being machined to a position close thereto, the carriage and the extension being so controlled that the splinter prevention block is automatically positioned for the period of time needed for machining, on each piece to be handled, in the region of the outgoing edge of the tool with respect to the direction of rotation of this.
