Abstract: The invention relates to a cutting subassembly for cutting off front and/or rear edge overhangs of panel-like workpieces. The cutting subassembly includes a saw unit which comprises a motor-driven saw blade which is mounted for displacement between a position above, and a position beneath, the workpiece. A contact element is associated with the saw blade and has at least one contact surface which may be engaged against the front or rear transverse side of the workpiece. The cutting plane of the saw blade may be oriented in alignment with the contact surface. The saw blade may be mounted such that it can be pivoted between a first operating position, in which it is oriented in alignment with the contact surface, and a second operating position, in which it is oriented obliquely in relation to the contact surface.

Abstract: In an edge gluing machine, a milling device (6) with a rotating milling tool (9) is provided for shaping the corners (7,8) of the projecting edge bands (14), its pivoting device (11) being arranged on a vertically adjustable housing (15). During the adjustment of the bridge (2) to the respective thickness of workpiece (3), the housing (15) is adjusted vertically by a displacing member (18) and by means of a limit switch (28,29) such that the pivot axis (11') of pivoting device (11) is located in the center of workpiece (3). A linear path control activatable by a light barrier causes the milling tool (9) to be positioned at half the thickness of the workpiece from the leading or trailing narrow surface of workpiece (3). The position of the pivot axis (11') is thereby determined such that a perfect machining of the corners (7,8) is ensured.

Abstract: A device for scoring workpieces, in particular, laminated panels, which are to be split up subsequently by a circular saw along the scored track, comprises a scoring head arranged in the direction of operation forwardly of the circular saw, and two scoring knives held stationarily on the scoring head and penetrating the workpiece surface, with their mutual spacing corresponding to the cutting width of the saw blade.

Abstract: A grinding disk with an interrupted, circumferentially contoured surface for sanding or polishing a respectively contoured work piece surface has a plurality of sector-type grinding disk elements secured to a hub for rotation with the hub. The disk elements are produced by first casting a straight longitudinal grinding body, which is then cut into said elements, which are secured to the hub with sector spaces between neighboring elements so that the circumference forms a polygon. Substantial savings are achieved because now the hub can be used repeatedly by merely replacing the worn-out grinding body made of the sector-type grinding disks.

Abstract: In guide rollers (2) for band saws, especially for sawing meat and bones, the contact surface (4) is very quickly fouled or soiled by greasy fat, bone meal, etc., which has a disadvantageous effect on the power transmission and the guidance of the band saw blade (3). The contact surface (4) of the guide roller rim which guides the band saw blade, is provided with open passages (7) reaching to the side surfaces (5) of the guide roller rim. Fat and other contaminating material is pressed by the band saw blade into the passages and is flung away from the rotating guide roller (2), whereby a reliable operation of the band saw is assured.

Abstract: A band saw for foodstuffs, especially meat and bones, has a housing with a door and spray nozzles operatively arranged inside said housing for spraying a cleaning liquid or drying air onto all saw components inside said housing. Thus, a complete and thorough cleaning and drying of all saw surfaces inside said housing is possible without any appreciable extra effor or man hours. Simultaneously, the environment of the saw is protected against soiling or wetting by the cleaning operation for the saw.

Abstract: A circular panel saw is supported by a slide (7) slidably mounted for up and down movement on a guide carriage (2) which in turn is mounted for horizontal back and forth movement on a substantially upright frame or rack (1). The guide carriage (2) has a carriage head (3) connected to a carriage foot (4) by a support beam (5) and an abutment beam (6) extending in parallel to each other and made of conventional sectional steel. These beams (5, 6) are die drawn or bright drawn whereby an inexpensive and simple construction of the guide carriage is possible. The die drawn beams require very little machining and a small or hardly any readjustment. Yet, the present saw makes accurate, straight cuts.

Abstract: A sanding tool (8) or surface finishing tool for sanding or finishing a work piece such as profiled moldings or edges of panel type work pieces has a foam material body (17), at least one surface of which has a contour corresponding to the cross-sectional shape of the surface to be sanded or finished. A sanding or finishing belt (11) is secured to the contoured surface of the foam material body. The tool is produced in a simple, economical manner by casting or molding. For this purpose a profiled body having a surface configuration corresponding to that of the work piece is inserted into a mold. A length of sanding belt or sandpaper is inserted into the mold so that the rough surface faces the profiled body. The mold is then filled with a foam material which, after curing, is intimately bonded to the sanding belt or paper with the desired contour.

Abstract: A molded body having a profiled cross-section, such as a grinding or polishing tool, is cast in a mold by pouring foaming synthetic material into a molding cavity closable on all sides except for holes in the end walls of the molding cavity through which a contouring insert member having a profiled surface extends to pass through the entire molding cavity and possibly even through several molding cavities arranged in axial alignment with one another. A sealing device (22) is provided adjacent each end wall for closing and sealing the profiled gap between the contouring insert member and the hole in the adjacent end wall. The sealing devices are adjustable to differently profiled inserts and assure that a molded body or tool is produced which has precise, prismatic and parallel surfaces and edges.

Abstract: An apparatus for melting and applying meltable adhesive, especially in combination with edge gluing machines for continuously advancing work pieces, includes a melting chamber (4) for the meltable granular adhesive material. The melting chamber is equipped with a heatable melting insert (5). A supply container (17) for the solid meltable granular adhesive material (18) is arranged to open into the melting chamber (4). A power driven closure slide (13) is arranged between the melting chamber (4) and the supply container (17) for the granular adhesive material. The closure slide (13) is operated in such a manner that filling the melting chamber (4) with granular adhesive material (18) is free of trouble and the adhesive material may be properly processed without any difficulties, especially without any jamming.

Abstract: The applicator for applying adhesive to a work piece, for example in an edge glueing machine for work pieces moving continuously through the machine, has adhesive discharge holes (6). The adhesive is supplied through these holes (6) under pressure to the edge of work pieces. Any contaminating particles, which may be present in the adhesive prior to its application to the work piece, tend to travel upwardly with the adhesive in the adhesive supply conduit (2, 4), due to their lower specific weight, whereby the contaminations may clog the discharge holes (6) and prevent the proper application of adhesive to a work piece. For avoiding such clogging the nozzle body (1) is provided with a scavenging duct (5) which is connectable to the adhesive supply conduit (2, 4) for repeatedly passing a portion of adhesive out of the supply conduit (4), whereby the application of adhesive may be performed without any trouble. The discharge holes (6) are closed during the scavenging of a small portion of adhesive.

Abstract: Apparatus for melting and applying meltable adhesive in which a separate melting insert including a melting wall is interposed between the melting chamber and the application device. The melting wall is formed with projections or cones, and channels for passing molten adhesive to the nozzle body of the application device. A piston in the melting chamber presses a unit of adhesive against the melting wall. The melting wall is independently heated by a heater and controlling temperature sensor. The nozzle body and melting insert/melting wall are formed of different metallic materials, the latter being made of light metal alloy for better thermal conducting response. The melting insert forming the melting wall is removable to facilitate the cleaning and maintenance.
