Patent number: 5427163Abstract: The present invention concerns a method for cutting squared timber into a number of thin boards. Individual boards 32 are cut off by a blade 30 from the squared timber in each of the successive cutting machines 14a-g, essentially in longitudinal direction of the squared timber. The thickness of the squared timber 26 is selected in such a way that, once an integral number of boards having a predetermined thickness are cut off, a residual board remains which is reduced to the same thickness d as the boards 32 by shaving. The shaving preferably takes place by placing a planer 18 after the last cutting machine 14g. The installation 10 is equipped with a material feed 12 and a conveying system 20 for removing the cut boards, the cutting machines and the planer are also connected to one another by conveying devices 16, 24.Type: GrantFiled: December 13, 1993Date of Patent: June 27, 1995Assignee: Firma Gebruder LinckInventors: Siegmar Gonner, Heinz-Hubert Braun

Patent number: 5390716Abstract: A machine is described for the slicing removal of a board from a cant adved longitudinally past a blade and pressed, from the side opposite from the blade, by means of a pressing device against the blade and a counterpressure rail mounted in front of the blade. In contrast to conventional constructions, in which driven feed rollers for the cant are located before and beyond the actual slicing device, driven roller pairs are provided directly in the region over which the blade, which forms a very acute angle with the feed direction, extends. The feed roller pairs are moreover floatingly journaled so that they do not affect the position of the cant. By the novel arrangement, an overly lengthy force transmission path through the cant itself from the feed rollers to the blade is avoided.Type: GrantFiled: December 10, 1993Date of Patent: February 21, 1995Assignee: Firma Gebuder Linck Maschinenfabrik "Gatterlinck" GmbH & Co.

Patent number: 5318083Abstract: An apparatus for severing thin boards from squared timber includes a guide urface upon which a squared timber is conveyed and pressed against a cutting edge of a blade, as well as a counter pressing edge. The adjustment of the distance between the guide surface and a plane parallel thereto which extends through the blade cutting edge (i.e., the thickness of the thin board to be cut) is effected by relative adjustment of the blade cutting edge to the guide surface in an inclined plane which forms an acute adjustment angle .alpha. with a line normal to the guide surface. Because of the relative adjustment of the blade cutting edge to the guide surface along the angle .alpha., when a different board thickness is desired, the distance between the blade cutting edge and the counter pressing edge in the cutting direction is automatically adapted. In a preferred embodiment of the apparatus, the width of an exit guide channel for the severed thin boards can also be simultaneously set to the desired board thickness.Type: GrantFiled: January 28, 1992Date of Patent: June 7, 1994Assignee: Firma Gebruder Linck Machinenfabrik "Gatterlinck" GmbH & Co., KGInventors: Siegmar Gonner, Heinz-Hubert Braun
