Abstract
An arrangement for feeding blocks of timber into a cutting machine has a stationary rear pair of lateral guide rollers immediately in front of the saw blades, a laterally displaceable front pair of lateral guide rollers and a middle lateral guide device, which may be a pair of lateral guide rollers. The middle lateral guide device is at half the distance between the front and the rear pair of lateral guide rollers. The front pair of lateral guide rollers is arranged on a support arm which can swing on a swivel point which is in front of the rear pair of lateral guide rollers at a distance of six tenths of a distance between the front and rear pair of lateral guide rollers. The arrangement is suitable for curved sawing both in sawing machines and in reducing and reducing sawing machines.
Claims12
An apparatus for feeding a block of timber along a feed path into a timber processing machine having at least one processing tool operating along a fixed centre axis, said apparatus comprising:
- first guide means for said block positioned directly in front of said processing machine, said guide means positioning the centre of said block substantially on said centre axis;
- second guide means for said block positioned a first distance from said first guide means, said guide means being movable perpendicularly to said centre axis to position the centre of said block a second distance from said centre axis;
- third guide means for said block positioned a third distance from said first guide means, with said second guide means positioned therebetween, said third guide means being movable perpendicularly to said centre axis to position the centre of said block a fourth distance from said centre axis;
- and
- control means for simultaneously moving said second and third guide means perendicularly to said centre axis in fixed relation to each other so that said second and fourth distances lie on an arcuate line which is tangent to said centre axis at said processing tool.
