ABSTRACT:
In order to improve a folding machine for joining the edges of two sheet-metal parts forming an angle between them by means of a folding procedure, comprising a machine frame, a folding carriage movable on the machine frame by a drive in a guide means extending along a folding direction, this carriage having at least one pair of folding rollers for folding the edges of the sheet-metal parts, and holding devices arranged on the machine frame for fixing the sheet-metal parts in position during the folding procedure, such that large, in particular, long sheet-metal parts can be handled in a simple manner on this machine and are easy to insert into it, it is suggested that the guide means be movable in an essentially vertical direction, and that the folding machine have support surfaces arranged on a supporting plane extending at right angles to the folding direction, the sheet-metal parts being placeable on these support surfaces with edges which extend transversely to the edges resulting in the fold.
