  • Publication number: 20080092989
    Abstract: The invention relates to a method and a device for loading a device for eccentrically slicing veneering. Known slicing devices are problematic in that the process for loading the same with a block of wood is relatively time-consuming and at least partly difficult to perform. The aim of the invention is thus to improve one such slicing device in such a way that the loading process is simplified and accelerated. To this end, a device for milling (2) grooves (3) comprises a measuring device (14) which is used to determine the cross-section of the block of wood (4); the position of the grooves (3) and the cross-section of the block of wood (4) can be recorded as data; and a grip device (17) and a tool carriage (5) of the slicing device (1) can be controlled according to the data in such a way that the block of wood (4) can be placed in the slicing device (1) and the tool carriage (5) is positioned in relation to the block of wood (4) in a starting position for the slicing.

  • Patent number: 7100650
    Abstract: The problem in previously known stay log-type veneer slicers in which a large block of wood is directed in an eccentrically rotating manner past a knife consists of the fact that a remaining block that cannot be sliced has to be removed by hand from a girder structure on which the block is mounted. Hence, the downtime for removing the remaining block and mounting a new block of wood is relatively long. The aim of the invention is therefore to create a stay log-type veneer slicer that has a reduced downtime. Said aim is achieved by disposing means for discarding the block of wood (16) and a device for automatically conveying away the discarded block of wood on the girder structure (12).

  • Publication number: 20050241453
    Abstract: In known veneer slicing blades, wherein a block of wood is guided in front of a blade in an eccentrically rotational manner, the relatively large remnants of large wooden blocks cannot be measured. If the residual thickness of the wooden block is small, the edges move away in an elastic manner from the blade, leading to tom edges and correspondingly bad veneer quality. The aim of the invention is to improve a staylog machine in such a way that an evenly high veneer quality can be obtained even in the event of extensive use of said block of wood. This is achieved by providing displaceable means for supporting the longitudinal ends of the block of wood (16) protruding from the bearing surface (15) on the timber-frame (12).

  • Patent number: 6913049
    Abstract: The invention relates to a veneer slicing machine. The output of prior art veneer slicing machines is limited by virtue of the fact that the slideways quickly heat up at a maximum stroke rate. As a result, the maximum permissible temperature of 120° C. is quickly reached thereby making it necessary to shut down the machine in order to permit the slideways to cool. The inventive veneer slicing machine should be able to be used in continuous operation at a maximum stroke rate and thus function without resulting in a loss in quality. To this end, cooling means are arranged on the slideways (16) and are provided in said slideways (16) e.g. in the form of borings (21) through which the coolant circulates whereby enabling heat to be carried away in a well-directed manner.
