ABSTRACT:
A conveying system includes first and second straight side supports arranged parallel to one another on opposite sides of a longitudinal axis. A plurality of roller structures is provided, each having opposite ends mounted in respective ones of the side supports. An endless web is mounted for travel along the rollers in the direction of the longitudinal axis. Each roller structure is associated with a set of mounting holes formed in the side supports, whereby each set comprises a first series of holes formed in the first side support and a second series of holes formed in the second side support. One end of the roller structure is mounted in a selected one of the holes of the first series, and the other end of the roller structure is mounted in a selected one of the holes of the second series. Each hole of the first series is aligned with a respective hole of the second series to form a pair of aligned holes. Each pair of aligned holes defines a rotary axis, and those rotary axes are oriented obliquely to one another whereby the associated roller structure can be removed from one of the pairs of holes and inserted into another of the pairs of holes to change an angle formed between the roller structure and the longitudinal axis.
