Machine for single-pass hide skiving

Hide skiving machine, comprising a supporting structure with two supporting sides, a driving cylinder rotatably connected to said sides, a first frame and a second frame both coupled in an oscillating manner to said sides, said first frame rotatably supporting a support cylinder which is arrangeable upon an oscillation of said first frame in a working position which is slightly forward and below said driving cylinder, thereby a hide being advanceable between said driving cylinder and said support cylinder, said second frame rotatably supporting a first bladed cylinder which is arrangeable upon an oscillation of said second frame in a working position which is slightly rearward of said support cylinder, thereby a hide being skivable between said support cylinder and said first bladed cylinder, said hide skiving machine further comprising a second bladed rotating cylinder rigidly associated with said supporting structure in a preset frontward position above said driving cylinder, and a third frame being associated with said first frame in an oscillating manner, said third frame supporting a contrast cylinder which is kinematically connected to said first support cylinder by means of a row of rollers interposed therebetween, said contrast cylinder and said rollers being arrangeable in a working position between said second bladed rotating cylinder and said support cylinder upon an oscillation of said third frame, thereby a selected skiving of a hide being effected between said contrast cylinder and said second bladed rotating cylinder.
