The conveyor belt (4) comprises one or more rows of slots (10) extending in the direction of movement of the conveyor belt, each slot (10) being so dimensioned that a lasted shoe upper can be supported bottom up by the conveyor belt (4) with the last cone projecting into the slot. The support means preferably comprises two portions, the first portion comprising lands (16) by which the belt (4) is supported adjacent the or each row of slots (10) and a trough aligned with said path of movement, and the second portion comprising a continuous support surface (20).
