Abstract: A conveyor belt has a mono-ply construction comprising a central fabric ply, top and bottom cover layers and a connection interconnecting the opposite ends of the belt. The top and bottom cover layers are removed from the opposite ends of the belt to define exposed fabric ply regions which are arranged in a mutually overlapping relationship. Two connection plates extend generally over the entire width of the conveyor belt on opposite sides thereof, and fasteners extend through the connection plates and the opposite ends of the conveyor belt to form a secure, yet flexible, connection.

Abstract: A press for extruding lubricating grease has a press head with a high pressure reciprocating pump, a high-pressure outlet opening with a check valve, a low-pressure intake opening for feeding the mass to be extruded to the reciprocating pump, and a connection on the press head for connecting a pipe thereto. The pipe receives therein a grease filled cartridge having a displaceable trailing piston. A cartridge-connecting element has a connection for the cartridge, and the pipe is open at that end thereof oriented away from the press head, whereby when the cartridge is connected to the cartridge-connecting element, it protrudes from the open end of the pipe, is guided radially by the pipe and is retained axially by the cartridge-connecting element.

Abstract: A conveyor belt connector and method includes a plurality of connecting elements mounted on opposite ends of an associated conveyor belt or the like. A plurality of connector fastening elements are received through the connecting elements and the conveyor belt to mount the connecting elements on the conveyor belt. At least one reinforcing strap is provided, and is closely received in a corner recess formed in one of the faces of the conveyor belt. The reinforcing strap extends longitudinally along the conveyor belt, and has one end thereof attached to the conveyor belt by at least one of the connector fastening elements. A strap fastener connects the opposite end of the reinforcing strap to the conveyor belt, whereby the reinforcing strap relieves stress at the opposite sides of the belt connector to provide greater strength and durability.

Abstract: This invention relates to a connection for two ends (2,4) of a conveyor belt (1), comprising connection elements (6) which are attached by means of fixing elements (7) to the conveyor belt ends (2, 3). A covering (17), which covers the connection elements (6) and the fixing elements (7) thereof, is disposed on at least one face of the conveyor belt (1). A fastener (21) for the covering (17) cooperates with the connection elements (6). In order to create a connection which is distinguished by its particularly prolonged durability, the invention essentially proposes that the respective fastener (21) is attached to one or both limbs (11) of the connection element of U-shaped form, or to a plate or to plates which are disposed on both faces of the conveyor belt and which rigidly connect the conveyor belt ends. (FIG. 2).

Abstract: The invention pertains to an installation for fastening a connecting elem (1), specifically a U-shaped one, to the end (9) of a conveyor belt (10) with a peg-shaped fastening element (7). The fastening element is pushed through entry openings in the connecting element and through the conveyor belt, and is deformed at least in the area of its preceding end by a ram (36) that has a deforming contour, and is located in a tool (16). According to the invention, there follows also a secondary deformation of this area by a pressure bar (38), which is brought into contact with the tool containing the ram and the deformed end of the fastening element, after the contour of the fastening element had been already deformed.

Abstract: A unique connecting pin is provided for splicing or lacing up conveyor belt egments. The connecting pin has multiple core pieces of defined lengths, aligned within the interior of a casing element. The casing element is constructed from a relatively soft material, which can give during operations, and the core pieces are aligned in such a way, that they extend through more than two coupling eyelets.

Abstract: A belt lacing is provided for conveyor belts of the type used in installans with a trough zone, where the conveyor belt is supported on both sides curved towards the top. The conveyor belt ends are joined together with a hinge joint or lacing, which is exclusively located outside of the curved sections of the trough zone of the conveyor belt. The hinge joint or lacing contains coupling eyes which are fastened to the conveyor belt and at least one connecting pin, which passes through the intermeshing coupling eyes. The conveyor belt excels because of the minor wear in laterally flexing transition areas of the conveyor belt during passage through the trough zone. Moreover, it is simply constructed and can be manufactured in an uncomplicated way.

Abstract: A method and tool (15) for securing V-shaped, open connector elements (14) o belt ends (1) in a manual operation use staples (8) that are driven by hammer blows applied to a punch held by the tool. Each connector element (14) has at least two shanks (11, 12) and at least one eye loop (13) interconnecting the shanks. The staples (8) are initially held in place for the driving by one shank (11) of the connector elements (14). The securing elements (8) first penetrate holes in one shank (11), then the belt end (1), and then holes in the shank (12), whereupon the free end pieces (53, 54) of the staples (8) are bent over in the tool provided with a die (29) for this purpose. The connecting elements (14) have downwardly projecting shanks (12) which extend initially away from the belt end. These shanks (12) are first pressed against the belt end (1) with a manually produced force increased with the aid of a tool mechanism providing a mechanical advantage.

Abstract: A manual belt skiver removes a top layer of material along an end edge of a elt in preparation for mounting a lacing thereon. The skiver has a base with a handle attached thereto, and a normally vertical contact surface adapted to slide along the end edge of the belt during use. A knife is mounted on the base, and has a thin flat blade protruding outwardly from the contact surface, with a straight interior portion and an upwardly turned outer tip. A pressure bar is mounted on the base, generally forward of the knife, and includes a foot which protrudes laterally outwardly from the contact surface, generally above the cutting edge of the blade to guide the blade through the belt.

Abstract: A unique fastener is provided for conveyor belts and the like, and includes body element with a U-shaped cross section, containing at least one generally semicircular coupling eyelet, and a fastening leg with an entrance slot for at least one fastening pin.

Abstract: A fastening arrangement is provided to interconnect the opposite ends of a elt or the like, and includes a plurality of individual belt fasteners arranged side-by-side across the width of the belt ends. The belt fasteners include mounting portions which are impressed into the opposing faces of the belt end, such that the overall width of the belt tends to thereby expand and distort. A longitudinally inelastic tensioning element is positioned along a major portion of at least one of the belt ends, and is attached thereto, so as to generally maintain the overall width of the associated belt end and resist distortion thereof.
