belts, for finishing or repairing conveyor belts or other
machine-tool belts; non-metallic flexible and extensible
couplings for agricultural roller balers and for conveyor
belts intended for industry, logistics and the mining
sector; flexible expansion joints for conveyor belts,
including belt joints for finishing or repairing conveyor
belts, by joining two free ends of an unfinished or damaged
conveyor belt and for round baling presses, conveyor belts

The present disclosure provides a washer having a generally circular shape and is used for supporting a screw head. The shank of the screw penetrates the central hole of the washer. When viewed from a planar perspective, the outer edges of the washer have a sinusoidal shape with depressions and elevations.
The jointing device for conveyor belts comprises elements (1) as shown, each formed by a flexible frame covered with a food-grade heat-welded material, said elements comprising teeth (2) and complementarily shaped recesses (3), such that the teeth (2) of a first element (1) can be inserted into the recesses (3) of a second element symmetrical to the first and also comprising teeth (2) and recesses (3). The frame is covered with a food-grade heat-welded material on the sides (6) of the teeth, the front of the teeth, the bottom (3a) of the recesses and inside passages (7) intended for a connecting pin. As a result, bacteria present in the materials being transported by a conveyor belt equipped with the jointing device of the invention cannot access same and said bacteria are also prevented from passing into the frame.

Clips for jointing devices of the ends of a conveyor belt
The present disclosure provides a clip assembly for jointing devices for a conveyor belt that includes a U-shaped clip intended to be secured and straddling an end of a conveyor belt with an overhanging of a front curved portion, or nose of the clip. The clip assembly further includes a tube secured in a front concave portion of each clip and a bracket having two cheeks secured to lateral ends of the tube. The cheeks are joined together at a rear by a connection portion. The securing of the cheeks is obtained by piercings on lateral ends of the tube. Branches of the clips are provided with through-holes to secure the clip with a stem. In one form, the branches of one or more clips in a set of clips are of unequal length.

The washer according to the invention has a generally circular shape and is used for supporting a screw head, the shank of which penetrates the central hole (7’) of the washer. When viewed from a planar perspective, the outer edges of the washer have a sinusoidal shape with depressions (9) and elevations (10).
The invention relates to clips (1) which comprise a generally U-shaped part intended for being attached so as to straddle one end of a conveyor belt with the curved front portion — or nose (1') — of the clip projecting beyond same. A tube (3) intended for being attached in the front concave portion (1'') of each clip comprises, attached to the side ends thereof, two flanges (4') of a bracket (4). Said flanges (4') are joined at the rear by a linking portion (4''). The flanges are attached by threading bores (4'b) on the side ends of the tube (3). The arms (2', 2'') of the clips are provided with through-holes (7) intended for rod attachment means (5). The arms (2', 2'') of every second clip are of different lengths.
