Abstract: A tool assembly (20) for folding a carrier (H) comprising a first pair of fingers (24a) for gripping a blank (B) for forming the carrier (H), a second pair of fingers (24b) for gripping the blank (B), the first pair of fingers (24a) being pivotally coupled with respect to one another, and the second pair of fingers (24b) being pivotally coupled with respect to one another, the first and second pairs of fingers being coupled to an actuator for movement between a receiving position and a gripping position wherein the fingers are operable to engage a blank (B) in the receiving position and fold said blank (B) when disposed in the gripping position, at least one pair of fingers being rotationally mounted to a body (42) of a tool head (22) and coupled to a drive mechanism (32a, 32b) for rotation with respect to the body (42), such that a first portion of the blank (B) is foldable with respect to a second portion.
