A lagging system for conveyor belt pulleys is provided that allows for significant flexibility in attaching lagging members to the face of the pulleys while also providing improved distribution of the lagging material on the pulley face, and doing this while avoiding the creation of unduly long and circumferentially wide gaps between adjacent lagging members attached on the pulley. The lagging system can include lagging strips having non-linear leading/trailing edges thereof to allow adjacent strips to be attached without the undesired gaps formed therebetween. Preferably, the strips have projecting portions with fitment spaces defined therebetween with the projecting portions being offset on either side of the strip axis so that portions from one strip can be interfit in fitment spaces of an adjacent strip with lagging material or tiles thereon overlapping the lagging material or tiles on the projecting portions of the adjacent strip in the circumferential direction.

Lagging system for conveyor belt pulleys

A belt fastener having an upper plate and a lower plate with holes which align with holes in a pair of belt ends, and bolts are inserted through the aligned holes of the plates and the belt ends, and nuts screwed onto the bolts, to connect the belt ends. A preassembled lower plate and bolt combination is provided in which bolts are retained in their respective lower plate apertures by washers disposed on the bolt shanks. The washers are disposed on the bolt shanks sufficiently close to the lower plate to maintain anti-rotational engagement of the bolts with the lower plate, and spaced sufficiently far from the lower plate to allow outward swinging of the bolts to an insertion position for insertion of the bolts through the belt holes in an outwardly swung position for subsequent drawing together of the bolt and belt ends. The washers are displaceable along their shanks into abutment with the lower plate and deformable under the pressure associated with clamping together of the plates about the belt ends, whereby the washers deform and fill in the spaces between the bolts and the lower plate. The washers are preferably formed with flexible resilient tabs about a central aperture, with the tabs being deflected by the bolt shanks when slid onto their shanks to prevent washer material from being scraped off the washer and into the threads of the bolt when the washer is initially applied to the bolt.
