An accessory assembly (1) of toothed belts (9), toothed conveyor belts (9a) or portions thereof, comprising a base piece (2), a first piece (3) and a second piece (4) with respectively a first, a second and a fourth coupling part (21, 31, 41). The first and the second coupling part (21, 31) are complementary to one another so that the first piece (3) is couplable above the base piece (2) in one or more predetermined positions and the fourth and the first coupling part (41, 21) are complementary to one another so that the second piece (4) is couplable above the base piece (2) in one or more predetermined positions. The first piece (3) comprises a third coupling part (32) complementary to the fourth coupling part (41) and which faces in an opposite direction to the second coupling part (31).

A spiral conveyor is described. The spiral conveyor provides an extremely open design. The open design creates and defines a very sanitary design. The combination of a cantilever frame construction (with no side frames) and the edge/side driven belting allows for superior access and cleanability. This access and cleanability are of paramount importance to the food market, where sanitation requirements are stringent to maintain food safety by preventing bacteria growth.

Provided are a glass transportation apparatus and a system including the glass transportation apparatus for manufacturing a multi-pane glass unit. The glass transportation apparatus includes a plate including a main surface facing a main surface of a glass pane, a gas blowing device configured to blow a gas towards the main surface of the glass pane such that the main surface of the glass pane is spaced apart from the main surface of the plate, and a conveyer including a belt having an upper surface and a plurality of pulleys configured to circulate the belt.

A tensioning system for a conveyor belt arrangement is provided. More particularly, but not exclusively, to a vertical belt tensioning system for an endless conveyor belt arrangement. The conveyor belt arrangement includes a drive pulley which is in use driven by an external drive, an idler pulley and an endless conveyor belt rotatably mounted about the pulleys. The conveyor belt arrangement also includes a belt tensioning arrangement for use in tensioning the endless conveyor belt, the tensioning arrangement including a displaceable take-up pulley, and an actuator for displacing the displaceable take-up pulley. The tensioning arrangement is characterized in that the displaceable take-up pulley is displaceable along a vertical axis.

A rubber belt retracting and deploying device for a belt conveyor includes a base, mounting frames, an upper caterpillar disk, a middle caterpillar disk and a lower caterpillar disk, wherein the lower caterpillar disk is fixedly connected between the symmetric mounting frames, and the middle caterpillar disk is movably connected between the symmetric mounting frames, and may longitudinally slide along the symmetric mounting, frames, such that the lower caterpillar disk and the middle caterpillar disk form a first clamping device; the upper caterpillar disk is movably connected between the symmetric mounting frames, and may longitudinally slide along the symmetric mounting frames, such that the upper caterpillar disk and the middle caterpillar disk form a second clamping device; each of the upper caterpillar disk, the middle caterpillar disk and the lower caterpillar disk is provided with a driving part.

A belt conveyor has a plurality of impact bars installed beneath a conveyor belt in transverse directions along a longitudinal direction of the belt in order to prevent the conveyor belt from sagging, and thus an operator can easily replace and check impact bars without stopping driving of the belt when replacing and checking the impact bars.
