Abstract: Drive unit with a rotating saw blade which is hinged inside of a protective hood, for connection to a robot, shaped by an enclosure that can be connected to the robot in which a shaft is positioned, by means of which the saw can be powered under intermediate connection to a gearbox. The saw blade is held between two firmly connected internal rings which are arranged on both sides of the saw blade and contain it, as well as being connected to each other. The rings are rotatably mounted within non-rotating external rings that are connected to the protective hood. The device that is formed by the saw blade, the internal rings and the external rings is fastened in a removable way to a drive hub that is powered by the gearbox.

The first air regulation member is coaxially coupled to the shaft and has a plurality of first air flow apertures positioned radially about the shaft. The elastic ring is configured and positioned to centrifugally deform and increasingly block the first air flow apertures.

Abstract: Blade for a knife of an apparatus for cutting off the rectum of slaughtered animals, wherein the ground section of the hollow cylindrical blade (11) is at a specific angle to the cutting edge (20) at the cutting edge of said hollow-cylindrical blade. The blade (11) is ground over a short portion (A) of its length with a first angle (?) and then in the axial direction on this portion with a second angle (?) which is smaller than the first-mentioned angle (?).

Abstract: A device for cutting free the colon of a slaughter animal has a cylindrical cutting knife and a guiding arbor with a suction channel. The device has two components, one of which is a tool and the other a robot connecting plate. The robot connecting plate has a connecting opening for vacuum, a connecting opening for water, a connecting opening for pressurized air to drive the pressurized air motor, and a connecting opening for exhaust air from the pressurized air motor. The connecting openings are connected to associated channels or passages in the tool in the assembled state of the tool and the robot connecting plate.

Abstract: A turning device for compressed air tools. which is operated by a compressed fluid, is provided with a housing and with a rotor, which is rotatably arranged in a front housing part and into whose turbine element the fluid, which is under pressure, can flow, has a braking arrangement and a switch for the compressed fluid. The switch which is operatively connected with the braking arrangement and is arranged on a rear housing part in line with a compressed fluid supply conduit. Such a turning device requires fewer components and can be stopped in a simpler and faster way by a fluid switch, in the form of a sliding switch, which encloses the rear housing part in the area of the supply conduit and is provided with axially oriented control pins, which are connected, fixed against relative displacement, with a brake disk of the braking arrangement.

Abstract: Knives (10, 20) for carving out meat slabs (1), whose cutting edges (14, 24) are ground in such a way that they do not cut into the rib bones (2), or back bones), and at the same time assure cutting as closely as possible to the rib or back bones.

Abstract: A turning device (11) for compressed air tools (10). which is operated by a compressed fluid, is provided with a housing (16) and with a rotor (12), which is rotatably arranged in a front housing part (17) and into whose turbine element the fluid, which is under pressure, can flow, has a braking arrangement (14) and a switch (36) for the compressed fluid, which is in operative connection with the braking arrangement (14) and is arranged on a rear housing part (21) in line with a compressed fluid supply conduit (26). So that such a turning device (11) requires fewer components and can be stopped in a simpler and faster way by means of a fluid switch (36), a sliding switch (36) is provided, which encloses the rear housing part (21) in the area of the supply conduit (26) and is provided with axially oriented control pins (41), which are connected, fixed against relative displacement, with a brake disk (44) of the braking arrangement (14).

Abstract: A revolving blade skinning device is provided with a pair of housing shells, a drive motor mounted within the housing shells, a blade support mounted to the housing shells, a blade mounted on the blade support for rotation relative to the housing shells, and a gear drive situated in the housing shells and connected to the motor and the blade support. The gear drive includes a drive wheel driven by the drive motor and a belt situated between the drive wheel and the blade support. The belt imparts motion from the drive wheel to the blade support. The axis of rotation of the drive motor lies in the plane defined by the blade.

Abstract: A revolving blade skinning device and blade is described, in which a revolving blade is rotatably arranged between two covers, and wherein the revolving blade is embodied such that cutting edge areas with constant cutting edge radii alternate with notches. In accordance with the present invention it is provided that the notches are embodied V-shaped and as cutting edges, that they respectively take up an angle of 10.degree. to 20.degree. and the cutting edge areas respectively an angle of 25.degree. to 35.degree., and that furthermore the revolving blade projects past the covers in such a way, that in the process the cutting edge radius of the revolving blade is maximally greater by 1.5 mm than the covers.

Abstract: A band saw wherein one of the pulleys for an endless band-like blade is movable toward and away from the other pulley to relax the tension upon or to tension the blade. The one pulley is permanently biased away from the other pulley by a relatively weak spring whose bias can be overcome by hand to facilitate the removal of a blade or the application of a fresh blade. In addition, the one pulley is normally biased away from the other pulley with a pronounced force by a package of dished springs whose bias upon the one pulley can be interrupted by a single-acting cylinder and piston unit whose piston is installed between the dished springs and a reciprocable carriage for the one pulley. The dished springs react against a support for the pulleys and bear against the piston.

Abstract: The invention relates to a compressed-air screwdriver including a tool spindle, displacable against the action of a spring; an automatic shutoff having a valve for the motor, which upon attaining a predetermined torque is turned off and a device whose actuation, after the automatic shutoff, permits the motor to be put back into operation so that a screw can be further tightened or loosened with increased torque.

Abstract: A motor-driven scraping tool has an elongated supporting element and a receiving head arranged on its free end portion in an adjustable member, wherein an adjusting device is formed by one bendable tongue which forms a guiding face of the receiving head and an adjusting screw which bends the tongue relative to the supporting element, or more particularly relative to a counterguide.

Abstract: An arrangement for removing skin of slaughtered animals has a housing substantially forming a handle, two cutting disks having a central plane corresponding to a central plane of the housing, a drive and transmission, a separating wall formed of one piece with the housing and separating the transmission from the cutting means as well as including a center plate extending substantially in the region of the central plane and a limiting plate extending substantially normal to the latter, a spacer ring abutting against the central plate and supporting the cutting disks, and two covers of which one cover is connected with the central plate and partially supports the eccentric shaft, and the other cover abuts against the limiting plate and is pressed against the spacer ring, wherein the central plate of the separating wall has a free end portion which is overlapped by end portions of the covers.

Abstract: A butcher's meat saw has a housing from which extends a flat guide plate having an edge along which is slidable a blade reciprocated by an eccentric-type drive mechanism within the housing. Either the edge of the guide or the edge of the blade is formed with a groove and the other edge fits in this groove. One of these edges is furthermore formed with laterally opened notches so as to facilitate cleaning of the saw.
