Fork (2,2') for bales comprising a frame provided with a connection interface configured for engaging with a movement element of an actuator machine, the following being directly or indirectly mounted on the frame: - a coupling member configured for mechanically coupling to a bale, - at least one clamping member (50,50') configured for hooking and clamping at least a first packaging portion of a bale when mechanically coupled to the coupling member, the at least one clamping member (50,50') being movable between a position proximal to the bale coupled to the coupling member and a position distal from the bale coupled to the coupling member, and - an opening member (60,60') configured for acting upon at least a second portion of the packaging with the at least one first portion of the packaging in a clamped condition by the clamping member (50,50') so as to release the packaging from the bale, wherein the at least one clamping member (50,50') comprises a plurality of teeth and a comb element provided with a plurality of prongs, and wherein the comb element and the plurality of teeth are slidably mounted in the at least one clamping member (50,50') with respect to one another so as to switch between a clamping condition in which at least one prong of the comb element is configured to occlude at least partially a space defined between a pair of adjacent teeth of the plurality of teeth, thereby clamping said at least one first portion of the bale packaging between a tooth of the pair of adjacent teeth and said at least one prong of the comb element, and a releasing condition in which the at least one prong is configured to release said at least one first portion of the bale packaging comprised in said space characterized in that the plurality of teeth is configured to penetrate at least partially into the bale coupled to the coupling member and in that the at least one clamping member (50,50') is hinged to the frame to switch from the proximal position to the distal position, by rotating about an axis of rotation and is connected to the frame so as to tilt about an axis orthogonal to the axis of rotation. -
