摘要

The roller assembly consists of rollers (9) in a housing (10) which can be adjusted for height by moving it along inside the lower frame member (2). The longitudinal movement of the roller housing is accomplished via a screw (24) which passes through a cantilever bracket (25) on the vertical edge of the frame to engage with a nut (27) and a transmission rod (28) connected to the housing. The cantilever bracket is preferably a metal or plastics strip with its lower end turned inside the lower frame member, while the vertical adjustment of the roller housing is achieved by interacting sloping surfaces (15,16) on fixed and moving components. Alternatively, these can be a transverse peg and a sloping slot.
