Abstract
A method and a device for bending a rod-shaped link blank into a substantially closed chain link, particularly while at the same time hooking the link blank into a chain end. According to the invention, the blank is brought into a first receiving position with one of its end portions located between, on the one hand, two rotatable abutment rollers disposed at a distance from each other and, on the other hand, a bending tool movable back and forth transversely between said abutment rollers. The bending tool is then brought to a position between the two rollers so as to bend said one end portion of the link blank. The link blank is then brought out from the abutment rollers and is placed in a second receiving portion with its other end portion located between, on the one hand, the abutment rollers and, on the other hand, the bending tool, and the bending tool is then again moved in between the rollers so as to bend said other end portion of the link blank, possibly while at the same time hooking said one bent end portion of the link blank into the last link of a chain end.
