Abstract: A transfer device for transferring stacks (4, 4a, 4b, 5, 5a, 5b), which have a cylindrical external shape, of products resting on one of their edges between a conveyor (1) set upstream for advance of the stacks (4, 4a, 4b, 5, 5a, 5b) in a direction (a) transverse to the generatrices of the aforesaid cylindrical shape, and a conveyor (2) set downstream for advance of the stacks In a direction parallel to said generatrices, or vice versa, the said transfer device being operatively set between said conveyor (1) set upstream and said conveyor (2) set downstream. The transfer device comprises at least one gripping assembly (3) for picking up and conveying a stack. Said gripping assembly (3) moreover turns, according to a motion of revolution. (C) about a first axis (X), between a position in which it engages a stack (4, 4a, 4b, 5, 5a, 5b), in a position (A) corresponding to an output end of the conveyor (1) set upstream, and a position (B) in which it releases the stack onto the conveyor (2) set downstream.

Abstract: A machine and a method for carrying out portioning of products in stacks having a pre-set length. One or more portioning stations are provided, in which there are present at least two elements for supporting the stack, the supporting elements being mobile in translation, parallel to the longitudinal axis of the stack, between an initial position of separation of the stack from the respective row and a final position distant from the initial position at a distance greater than or equal to the pre-set length of the stack.
