Abstract: Saw belt roller, in particular for horizontal belt saws, in which the peripheral or running surface (3) carrying the saw belt consists of a wear-resistant, hard, metal material. The metal joining piece (6) between the running surface (3) and the hub (5) of the saw belt roller (1) is interrupted by the insertion of a noise-damping, in particular viscoelastic, material (7), which is preferably selected from concrete polymer, silicone, rubber, in particular hard rubber, or similar elastomeric material.

Abstract: A method of mounting cutters (3) or the like of high-alloy tool steel on a tool supporting member of metallic material, especially on the master disk (2) of a circular saw blade (1) or the supporting band of a ribbon for a band saw, by providing intermediate pieces between supporting member and cutters, in which the cutters (3) of high-alloy tool steel are initially welded individually and in soft or non-hardened condition onto an intermediate piece (4), and in which subsequently the intermediate piece (4) including the cutter (3) is subjected to heat treatment to harden the cutter (3) and simultaneously temper the intermediate piece (4), whereafter the intermediate piece (4) with the cutter (3) is welded onto the supporting member (2). Tools made in accordance with such a method are therefore distinguished by cutters (3), of high-alloy tool steel which are welded via an intermediate piece (4) to a tool supporting member (e.g. the master disk (2) of a circular saw blade (1)).

Abstract: An apparatus for sorting cut lengths discharged from an automatic metal cutting saw, includes at the discharge side of the saw, a movable endless link conveyor belt; a drive motor for driving the conveyor belt in a moving direction; a plurality of partitions arranged in spaced relation in the moving direction of the conveyor belt; a plurality of receiving bins arranged on opposite sides of the conveyor belt and mounted on the partitions, the receiving bins having different dimensions for receiving cut lengths of different dimensions, the receiving bins being spaced at predetermined lengths from the source; a mounting assembly for mounting the partitions for movement in the moving direction of the conveyor belt; a travelling distance sensor operatively connected with the drive motor; tipping cylinders located beneath the conveyor belt for tilting the conveyor belt downwardly on either side thereof; and a control assembly connected to the sensor and to the tipping cylinders for controlling the tipping cylinders

Abstract: A cutting tooth, viz. roughing tooth (2) and finishing tooth (3) made from cutting metal for a metal slitting saw, especially a circular disk saw, the geometry of said tooth being determined by the primary clearance angle (.alpha.), the rake angle (.gamma.), the radial clearance angle (.beta.), the tangential untoleranced dimension (s-e) and a tangential land (12) on the finishing tooth (3) with a negative relief angle (.epsilon.), in which for both the roughing tooth (2) and the finishing tooth (3) the cutting edge (7; 7', 7") is stabilized by a negative land (5; 5', 5"), and in which the angle (.chi.) between land and chip breaker face (4) is about 190.degree. to 240.degree., especially about 205.degree. to 230.degree..

Abstract: Transport device for rod-shaped material (16) for feeding a processing machine, in particular a metal saw, with rake-type supporting rails (2, 10) extending in the feed direction, and with a roller bed (14, 15) located transversely at the front end of the support rails (2, 10). In each case two supporting rails (2, 10) are arranged side-by-side, one of which is fixed and the other is movable along a closed curved track. The movable supporting rails (10) are arranged and their movement is selected in such a manner that their front ends extend through the roller bed (14, 15) and underrun its delivery plane in their lowermost position. At the front ends of the movable supporting rails (10) push-out angles (11) are attached, by means of which remaining rod material (17) can be pushed from the roller bed (14, 15) onto a depository (12), which is located at that side of the roller bed (14, 15) which is opposite the rake-type support rails (2, 10).
