A spiral conveyor is described. The spiral conveyor provides an open design. The open design creates and defines a sanitary design. The combination of a cantilever frame construction (with no side frames) and the edge/side driven belting allows for access and cleanability of the spiral conveyor.

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 fastener (1) comprising a) a fastener member (2) and one or more tenons (41,42,43) arranged on the front face (21) and being spaced apart from each other in said elongation direction (3), and b) at a proximal end (22) of the fastener member (2) a protrusion (5) comprising one or more fastener hinge knuckles (61,62). The fastener can be used to simultaneously join the ends (81,82) of a conveyor belt (8), the ends being designed tor form with a lace pin an end joint in the form of a continuous hinge (12), and the ends (1101,1102) of a corrugated sidewall (110) that is attached to the conveying surface (83) of the conveyor belt (8).
