VENEER LATHE AND METHOD OF PRODUCING VENEER

The veneer lathe (1) comprises rotatable spindles (3) for engaging the ends of a block (2)， a centering device (4) for measuring dimensions of the block (2) for determining optimal centering of the block (2)， the centering device (4) comprising centering spindles (5a， 5b) for engaging each end of the block (2)， transfer arms (6a， 6b) moveable in the axial direction of the spindles (3) for engaging the ends of the block (2) and in a direction that is perpendicular to the axial direction for transferring the block (2) from the centering device (4) to a peeling position， a knife assembly (35) comprising a knife (7a) and a nose bar (7b)， which is in the form of a rotatable roll， and a support device (8) comprising a lower roll (8) and an upper roll (8b) at a distance from the lower roll (8a) for supporting the block (2) during peeling.

编号为1的单板旋切机（veneer lathe）包含以下组成部分：用于夹持木段（block）端部的可旋转主轴（rotatable spindles）；用于测量木段尺寸以确定其最佳对中位置的对中装置（centering device），该对中装置配备有用于夹持木段两端的对中主轴（centering spindles）；沿主轴轴向移动、且可沿垂直于轴向方向运动的传送臂（transfer arms），其作用为夹持木段端部并将木段从对中装置传送至旋切工位；刀架组件（knife assembly）包含切刀（knife）和辊式压尺（nose bar，该部件为可旋转辊结构）；支撑装置（support device）包含下托辊（8）和与下托辊（8a）保持设定间距的上托辊（8b），用于在旋切过程中对木段进行支撑。
