ABSTRACT:
Conveyor apparatus of the non-endless type useful in combination with a press having a stationary lower bed or platen and an upper platen supported above the lower platen by means disposed along the opposite longitudinal sides of the platens. The conveyor apparatus includes feed and take-up rolls, one at each end of the bed, and belt means extending between the rolls and over the bed. Distinct cradle means support each of the rolls for rotation about horizontal axes. The arrangement is such that when the belt means is worn or broken the feed roll and/or the take-up roll may be vertically disengaged from the cradle means thereby to facilitate rapid replacement of the belt means.
The conveyor apparatus also is provided with first and second drive means, connectd respectively to the take-up roll and the feed roll, which are individually operable to rotate the rolls about their respective axes to move the belt in a forward direction and in a reverse direction. First and second brake means connected respectively to the feed roll and to the take-up roll are individually operable to provide resistance to the rotation of one roll when the other roll is being driven, thereby to maintain the belt in a taut condition during movement thereof in the forward direction and in the reverse direction.
