Abstract:
A lagging system for attachment to surfaces of pulleys of various diameters for transmitting drive forces of the pulleys rotating about a drive axis thereof to conveyor belts extending in a circumferential direction around the pulleys and in a lateral direction across the width of the pulleys between ends thereof substantially perpendicular to the circumferential direction, the lagging system comprising:a plurality of elongate lagging strips each having a carrying member and lagging material supported thereon for being fit and attached about the pulley surface in driving engagement with a conveyor belt; a predetermined length of each of the lagging strips that is generally sized to approximate the width of the pulley to which the strips are to be attached so that the strips are to be attached to the pulley with the strip length extending in the lateral direction; a predetermined effective width of each of the lagging strips less than the predetermined length and extending in the circumferential direction with the strips attached to the pulley; a first lagging strip of the plurality of elongate lagging strips; an elongate leading edge of the lagging material of the first lagging strip generally extending lengthwise along the strip and having a predetermined configuration such that the leading edge is in non-coplanar relation with the pulley drive axis; an elongate trailing edge of the lagging material of the first lagging strip generally extending lengthwise along the strip and having a predetermined configuration such that the trailing edge is in non-coplanar relation with the pulley drive axis; a second lagging strip of the plurality of elongate lagging strips for being attached to the pulley surface adjacent the first lagging strip; an elongate leading edge of the lagging material of the second lagging strip generally extending lengthwise along the strip and having a predetermined configuration such that the leading edge is in non-coplanar relation with the pulley drive axis and is generally matched to the predetermined configuration of the trailing edge of the first lagging strip; an elongate trailing edge of the lagging material of the second lagging strip generally extending lengthwise along the strip and having a predetermined configuration such that the trailing edge is in non-coplanar relation with the pulley drive axis and is generally matched to the predetermined configuration of the leading edge of the first lagging strip; and the carrying members of the first and second lagging strips each including an outer periphery having a predetermined configuration that generally follows that of the respective lagging material leading and trailing edges to allow the adjacent strips to be attached close to each other on the pulley surface.
