Abstract

Uprights of so-called omega type for pallet racks can be adapted for different loading situations and uprights of different dimensions can be roll formed in a single machine by the following consecutive roll forming steps:
- forming of a centre groove (12) consisting of two S-bends (15, 16) that are the same for different uprights, but with preselected distance from the middle of the blank to afford the desired width of the centre groove,
- roll forming of two S-bends (19) which are the same for different uprights but with preselected distance from the middle of the blank, and
- roll forming of two corners (22, 23) between the S-bends and at preselected distance from the bends of the centre groove to bend upward the webs (13, 14) of the upright.
The pallet racks with uprights of omega type have struts of square tubes (41,42) placed alongside each other and clamped together between indentations (18) on both webs of the uprights.
