Abstract: A hinged fastener for splicing transverse ends of conveyor belts together with the belt fastener having teeth that are bent from one of the fastener plates for piercing and sinking into the belt to increase the holding power of the fastener. In the preferred form, the fastener is attached to the belt end with two rivets with the teeth being adjacent the rivets to provide a small, low cost, high performance fastener. The teeth are formed by bending them down from the outer edge of the plate and about a bend line parallel to the inner edge of the plate so that the teeth face the belt end to keep the teeth from being pulled through the belt material. The location of the teeth adjacent the rivets maximizes the depth of penetration of the teeth into the belt for improved fastener holding power and minimizes the likelihood that the teeth will be bent upward and lose holding power when the belt is highly tensioned.

Abstract: A method of splicing a belt in a round baler having a bale forming chamber defined by at least one elongated belt having opposing ends spliced together to form a continuous band. The splice includes a first and a second series of similar side-by-side loops connected to and extending from the respective opposing ends of the belt, and an attaching element extending through both series of loops to maintain the opposing ends of the belt in alignment and close proximity to each other. Retention components affixed to the attaching element retain it in operative relationship to the loops and are disposed outwardly of the outer loops.

Abstract: The invention refers to a conveyor belt connecting element provided with a loop with leg-like extensions, the loop being intended to accommodate a coupling rod, as well as with openings in the leg-like extensions for inserting staples that serve to attach such connecting elements to the end of a conveyor belt. The essence of the invention is that the particular leg of the conveyor belt connecting element against which the free end of the staple legs rest, is provided with sloping contact surfaces for the free ends of the staple legs, and that the respective slope runs from the openings, provided for the staples, towards the loop as well as in the direction of the conveyor belt.

Abstract: This disclosure shows a novel shaped pintle wire for papermachine clothing. The intended use of the pintle wire is to close a pin seam by joining the loops formed by the machine-direction yarns at each end of an open-ended papermachine fabric. The present pintle has a non-circular cross section with a major dimension and a minor dimension. The major dimension stretches the loops and reduces seam gap. The minor dimension is approximately equal to the thickness of the fabric under load. Both serve to reduce the marking of the paper sheet by the seam region.

Abstract: A seamed papermaking fabric having a multilayer base fabric includes an endless woven fabric forming a tubular belt that is flattened to form a base fabric with at least one helical coil seaming member inserted between opposing sidewall portions at each respective lengthwise extremity of the base fabric. The helical axes of the seaming members extend transverse to the lengthwise direction of the fabric and the coils of the seaming member extend through spaces between adjacent machine direction yarns and supportably engage the machine direction yarns. The opposed lengthwise extremities of the base fabric are joined together by interengagement of the coils of the respective seaming members and insertion of the pintle member axially through the interengaged coils to form a seamed endless fabric of substantially twice the predetermined thickness.

Abstract: A fastener for conveyor belting has a plurality of fastener elements form a strip adapted to join the ends of the of conveyor belting with the aid of a coupling rod. Each strips forms one half of the fastener and its parallel connecting elements have legs and eye lugs for the purpose of forming eyes to receive and encompass a coupling rod after the legs of the two halves have been secured to the two belt ends and after the two belt halves have been brought into alternate interlocking engagement. The elements are secured to the ends of the belting by using pin-like fastening means such as staples. A non-leaking connection and a grease lubrication of the coupling rod are provided by a caulking filler in the form of a molded body of a rubber elastic material with eye lug grooves and fin elements which are aligned with the respective eye lugs of the connecting strip as an extension thereof and the molded body encompasses the coupling rod at least in part.

Abstract: The use of a spiral seam construction to join together the ends of a flat woven papermaker's felt having flat monofilament lengthwise yarns of a synthetic, polymeric resin improves the resistance of the seam to flex fatigue.

Abstract: The disclosure is of a seam construction for multilayered corrugator belts. The construction comprises woven complementary seam-halves joined by pintles and in which each seam-half comprises 2 connectors, each being a single and a double layer zone mechanically bound by the nature of the weave and in which the crosswise yarns of each connector form alternately displaced loops on one edge thereof which can be intermeshed with like loops formed on the edge of the opposite connector. The connectors are attached to a step in each end of the multilayered corrugator belt.

Abstract: A connector strip for conveyor belts includes a plurality of preshaped inidual connector elements (1) which are held together by a wire (2) secured to the inside of a leg of each connector element (1). The wire has a wave form shape whereby the bendability of the connector is maintained.

Abstract: A multi-layer papermarker's fabric is proposed wherein a helical coil is engaged individually with each of the plies of the fabric to define side-by-side loops protruding from the fabric end for interdigitation with corresponding loops at an opposed fabric end to receive a pintle wire, the arrangement being such that, in use, one ply of the fabric protects the helical coil and its connection with another ply of the fabric against wear and damage.

Abstract: A fastening device for fastening together flexible belts having reinforcing cords therein and a method of fastening in which damage to the reinforcing cords of the belts is minimized. The fastening device may also be utilized to attach a rigid plate having an aperture therein to a flexible belt having reinforcing cords therein to minimize damage to the reinforcing cords of the belt.

Abstract: The respective ends of a heavy fabric, for example, a woven dryer fabric or felt each provided with an array of connectong loops are joined with the help of a gap closing device. The gap closing device is detachably attached to the fabric when the latter is supplied to the user. When the fabric is being installed on the machine, the ends are pulled together by the gap closing device so that the arrays of loops are held in proximity and easily intermeshed to form an elongated tubular passage. A pintle wire is inserted into the passage to complete the joint. The gap closing device is then removed. A preferred gap closing device is a slide fastener, of which one tape is detachably attached to each end of the heavy fabric.
