Rotary cutterblock and method for its manufacture

Process and device for separating or slitting a rigid material

A process and a device are used to separate or slit a rigid material (30), especially wood, with a modulus of elasticity of preferably approximately 50,000 to 400,000 kg/cm. A narrow tool having chip-removing elements (16), especially a circular saw blade (15), produces a kerf (36) of finite width in the material (30) at a cutting speed of more than approximately 40 m/s. After the chip-removing elements (16) have passed, a separator element (20) bends a side piece (33) out of the kerf plane (3-7) so that after the chip-removing elements (16) have passed, the side piece (33) is always at a distance from the tool. When viewed along the feed direction (31) of the material (30), the separator element (20) is provided, at a distance from its periphery (22), which is contiguous to the tool and is first to come into contact with the material (30) when the material (30) is fed in, with a hump (25). An imaginary connecting line (35a) runs between the hump (25) and the chip-removing elements (16) at a distance (40) above a first section (23) of the separator element (20) lying between hump (25) and periphery (22).

DEVICE FOR FIXING A CHISEL ON A ROTARY SUPPORT OF A WOOD WORKING MACHINE

L'invention concerne un dispositif de fixation d'un ciseau sur un porte-ciseau tournant d'une machine de travail du bois. Le dispositif comporte un boulon de blocage s'engageant dans une fente ménagée dans le porte-ciseau, la tige du boulon maintenant le ciseau en position à l'aide d'une plaquette de biocage et comportant un prolongement transversal qui est pourvu de cames de sécurité s'engageant dans des évidements ménagés dans la fente de blocage de façon que ledit prolongement transversal soit bloqué en place dans une direction radiale. Application à des machines de travail du bois. The invention relates to a device for fixing a chisel to a rotating chisel holder of a woodworking machine. The device comprises a locking bolt which engages in a slot in the chisel holder, the shank of the bolt holding the chisel in position with the aid of a biocage plate and comprising a transverse extension which is provided with cams for safety engaging in recesses made in the locking slot so that said transverse extension is locked in place in a radial direction. Application to woodworking machines.

Knife Clamping System

An improved knife clamping system for use in an apparatus for processing wood, such as a flaker, chipper or waferizer, that employs a rotary disc or ring (2), cutting knives (10), holding locations (8) mounted on the disc or ring (2) to receive the cutting knives (10), clamping members (35) to engage and hold the cutting knives in position and fasteners (36) to mount the clamping members to the holding locations. The improvement comprises providing a surface (30, 40) having an undulating profile to engage against the cutting knives (10). The undulating surface can be formed on the clamping member (35), at the holding location (8) or at both locations. The surface is shaped to deform to engage the cutting knives (10) with a uniform clamping load upon securing of the fasteners (36) to a pre-selected torque. The foregoing arrangement requires fewer fasteners (36) while still maintaining an adequate clamping force on the cutting knives (10). This makes parts less expensive and reduces the time to change the knives (10) as there are fewer parts to loosen and tighten.

Improvements in Cutter-holders for Wood-working Machinery.

9820. Elsworth & Sons, J., and Fenton, R. April 22. Cutter - heads.- Relates to a cutterholder for planing and irregular moulding -machines of the type in which two oppositely-arranged cutting- tools are mounted so that rotation in either direction automatically bring, the cutter arranged for that direction of rotation into action. The tools K, L are secured by a nut J between a washer H and flange G on a tubular p:ece F, which is pivoted eccentrically at M to a flange C on a sleeve B secured by a nut E and washer R to the cutter spindle A. Owing to the difference in the internal diameter of the piece F and the external diameter of the sleeve B, on the direction of rotation being reversed, the sleeve F swings on its bearings N, P about the pivot M, and brings the opposite cutting-tool into the cutting position, as shown by the full and dotted positions of the tools in Fig. 4.
