ABSTRACT:
The present invention relates to a device for permitting adaptation of a suction pad (6) to the outer shape of products (1) to be lifted, whereby at least two brackets (13, 19) via links are pivotally connected to a carrying member (8), whereby at each bracket via links are pivotally arranged at least two supports (17, 18 and 23, 24) on which the suction pad is provided and whereby the supports are movable relative to each other. For the supports (17 and/or 23) to provide such a large degree of rotation that the suction pad (6) can adapt to products in the form of paper rolls (1) with substantially different diameters, one of the brackets (13, 19) is rotatably mounted on the carrying member (8) through a double link (11a, 11b) in order to permit a large degree of rotation between the bracket (13) and the carrying member (8) whereby one (17 and/or 23) of the supports (17, 18, 23, 24 ) is provided on each bracket (13 and/or 19) through a double link (15a, 15b and/or 21a, 21b).
