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.

Abstract: A machine for machining workpieces, such as panels, planks, and sections. The machine includes a conveyor for conveying workpieces in an infeed direction past a plurality of operating stations fixed in position along a conveying line. A carriage cooperates with the conveyor to support and feed the workpieces. The carriage is coupled with the conveyor for conjoint movement in the feeding direction of the workpieces. The carriage cooperates with other members to form articulated quadrilateral that supports a bar in such manner that the angle formed between the axis of the bar and the conveying line is adjustable. The bar, together with the conveyor, provides support for workpieces being machined.
