1. A conveying apparatus comprising:

  • a support structure including first and second straight side supports arranged parallel to one another on opposite sides of a longitudinal axis;

    a plurality of roller structures each having opposite ends mounted in respective ones of the side supports; and

    an endless web mounted for travel along the rollers in the direction of the longitudinal axis;

    each of the roller structures being associated with a set of mounting holes formed in the first and second side supports, whereby each set of holes 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 associated roller structure being mounted in a selected one of the holes of the first series, and the other end of the associated roller structure mounted in a selected one of the holes of the second series;

    the holes of each series being spaced apart in a direction parallel to the longitudinal axis;

    each hole of the first series being aligned with a respective hole of the second series to form a pair of aligned holes, each pair of aligned holes defining a rotary axis, the rotary axes of the pairs of holes of each set of mounting holes being 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 between the roller structure and the longitudinal axis.
