Patent ID: 7010952

Claim:
In a system comprising a rolling machine used to form work pieces, a device for holding at least one roller in the rolling machine comprising: at least one roller that can rotate about a rotational axis; at least two holding arrangements arranged on opposite faces of the at least one roller viewed in the direction of the rotational axis; at least two coupling arrangements that can be configured in a coupled mode and an uncoupled mode, wherein the at least one roller can be detached from the two holding arrangements when the at least two coupling arrangements are in uncoupled mode, and wherein the at least two coupling arrangements comprise: a first coupling part including at least a first groove and a second groove that does not run parallel to the first groove; and a second coupling part including at least a first coupling element that projects further outward from the second coupling part than a second coupling element, such that when the at least two coupling arrangements are in coupled mode: the first coupling element of second coupling part extends into the first groove of the first coupling part; and the second coupling element of the second coupling part positively engages the second groove of the first coupling part.
