Abstract: A corrugator belt for a corrugator machine has a base joined into endless from by means of a clipper seam. The base has a first end and a second end, and a first side and a second side. A strip of compressible material wraps around each of the first and second ends from the first side to the second side, and the clipper hooks for the clipper seam are installed over the strips at each end. The compressible material of the strips protrudes between adjacent clipper hooks to prevent corrugated paper board being manufactured using the corrugator belt from firmly contacting the clipper hooks and being marked and otherwise damaged by them.

Abstract: A connector for conveyor belts and the like includes a plurality of connection elements disposed in a side-by-side relationship to extend across the end edge of an associated belt. Each of the connection elements includes outwardly disposed shank portions with free ends shaped for insertion into the opposite faces of the belt, and inwardly disposed loop-shaped center portions arranged to mesh with a like connector on the opposite end of the belt. A generally flat cover element has a central aperture through which the center portions of the connection elements are inserted, and is deformable for folding the cover element over the end edge of the belt and onto the opposite faces of the belt to cover the shank portions of the connection elements on both sides of the belt.

Abstract: This invention provides a belt for bending a glass sheet without surface defects caused by roller marks, belt junctions or belt deformations. A strip of heat-resistant member is joined together while the ends of the heat-resistant member are arranged so that they are not exposed at the surface defined by an endless track for bending the glass sheet. Alternatively, fitting portions are arranged along the endless track, and the glass sheets are bent while these fitting portions prevent a deformation of the belt. Bent glass sheets can be manufactured efficiently and without surface defects by bending the sheets while conveying them with such a belt.

Abstract: A fastener for splicing ends of conveyor belts together is provided having a rivet that is pre-inserted thereto to provide speed and ease in installation. The rivet is held in an aperture of the upper plate by an interference fit at the lower end thereof. Preferably, the interference fit is achieved by knurling of the lower end portion of the rivet shaft to create raised interference portions or ridges integral therewith that are sized to be in an interference fit in the upper plate aperture. The remainder of the shaft can be sized to provide clearance between it and the aperture. An applicator machine tool is also provided for automatically securing a strip of the pre-inserted rivet fasteners to a belt end in a fast and efficient manner. The tool uses operating members to first drive pilot nails through the belt lower surface into registry with the rivets, and thereafter the rivets are driven coordinated with the pilot nails that are withdrawn back through the belt.

Abstract: A fastener is provided for splicing end portions of conveyor belts together with the fastener having a bolt with a pilot or lead-in portion that provides improved threading of a nut thereto and makes installation of the fasteners on the belt ends faster and easier. The pilot of the bolt is longer than the beveled conical tip portion of prior bolts so that nuts received thereon will stay substantially aligned with the axis of the shank. In this manner, threading of the nut to the bolt shank is easier in terms of avoiding cross-threading problems. Also, as the pilot portion of the shank is free of any threads, the installation of the bolt onto the belt ends can be done more quickly with less resistance during the insertion process.

Abstract: The invention is a seam for joining opposed ends of a belt for recirculation in machines. The seam comprises a reinforcing wire and at least two elongated coupling elements, each of which extends in the transverse belt direction. Each of the coupling elements comprises first and second sides and a row of coupling loops along the first side. The reinforcing wire extends through one of the coupling elements adjacent the second side. Coupling loops of two adjacent coupling elements are cooperable in such that they may be overlapped to result in a passthrough channel extending in the transverse belt direction and through which a coupling wire can be inserted. Each of the coupling elements is configured as a tubular coupling sleeve having cutouts. The cutouts are configured complementarily to the coupling loops such that coupling loops of one coupling element of a pair of adjacent coupling sleeves fit into cutouts of another coupling element of the pair of adjacent coupling elements.

Abstract: Splice joint for plastic coated fabric conveyor belt or similar article which initially provides a mechanical bond between the two (2) conveyor belt ends to be joined prior to a vulcanization process. This is achieved by providing a “jig-saw puzzle” splice between the two (2) conveyor belt ends to be joined wherein at least one of the conveyor belt ends to be joined has outwardly extending mushroom shaped or arrow-head shaped tabs and the other conveyor belt end to be joined has corresponding inwardly extending sockets to provide both increased splice joint surface area, as well as a mechanical bond, between the two (2) conveyor belt ends to be joined.

Abstract: A seam arrangement for connecting the two ends of a fabric so as to form an endless belt, particularly for use in papermaking. The seam arrangement comprises two endless coils (10) which are respectively located at the free ends of the fabric and on interdigitation are brought into union by a pintle wire. Each loop of the coils (10) is secured by a “short” fabric loop (22) and a “long” fabric loop (18). The short fabric loop is located at the right hand side of the long fabric loop when looking up the fabric towards the seam.

Abstract: A connector assembly for a draper belt in a harvesting machine having first and second connecting bars on opposite sides of belt end flanges. One connecting bar has a plurality of bores while the other has a plurality of fixed studs. The studs project through the apertures in the belt end flanges and the bores in the first connecting bar. The connecting bars are held together by lock nuts. By fixing the studs to the connecting bar, separate bolts are eliminated and only one wrench is needed to drive the nuts. Lock washers are eliminated by the use of lock nuts.

Abstract: A length of conveyor belt is provided with end sections of fusible material, such as the thermoplastic material, at opposite ends.

Abstract: A strip of riveted belt fasteners is provided manufactured in a punch press or the like to form multiple belt fasteners at a time with the fasteners each being attached to an end of a conveyor belt by way of a single rivet extending through single apertures in upper and lower plates of each of the fasteners. The small fasteners herein are provided with sufficient strength to be used in abusive hay baler applications while the fasteners must travel about small pulleys, e.g. 3″ to 3.5″ inches in diameter. Further, the installation of this rivet belt fastener in the field is about as simple as driving a nail requiring a portable applicator tool and a hammer. That is, the fasteners can be riveted attached to the belt end by way of a low cost applicator tool that includes recessed hardened anvil surfaces integrally formed in the body thereof to upset initially rivets which are driven through the belt with a separably attached pilot nail.

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.
