Abstract
Abstract The invention relates to a slicing machine having a hydraulic feed means, a piston pump synchronized with the rotation of the knife so that for each revolution of the knife a measured amount of fluid is supplied by the pump to the feed means thereby determining the increment of movement and thus, the slice thickness. The stroke length of the piston pump may be varied to change the slice thickness.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
117 words
A slicing machine comprising a rotating knife and an advancing means for the object to be sliced, said advancing means being movable substantially perpendicular to the plane of rotation of the knife by means of a hydraulic cylinder, characterized by a piston pump, means for driving said piston pump in synchronization with the relative movement of the knife and the object in the plane of rotation of the knife by which the object is cut up in such a manner that the piston pump performs a stroke for each cutting operaton, said piston pump feeding hydraulic fluid to the cylinder during the advance of the object for stepwise advancing the cylinder plunger connected to the advancing means.
Claim 2
Dependent Claim
117 words
A slicing machine comprising a rotating knife and an advancing means for the object to be sliced, said advancing means being movable substantially perpendicular to the plane of rotation of the knife by means of a hydraulic cylinder, characterized by a piston pump, means for driving said piston pump in synchronization with the relative movement of the knife and the object in the plane of rotation of the knife by which the object is cut up in such a manner that the piston pump performs a stroke for each cutting operaton, said piston pump feeding hydraulic fluid to the cylinder during the advance of the object for stepwise advancing the cylinder plunger connected to the advancing means.
Claim 3
Dependent Claim
99 words
A machine according to claim 1 and in which the pump piston is spring loaded and activated by a curved disc rotating in synchronization with the knife, characterized in that the pump is mounted in a housing which is pivotable about an axis parallel to the axis of the curved disc and that the free end of the piston rod of the pump abuts in and is displaceable along an arm, one end of which is mounted rotatably about a third axis parallel to the two first axes and the other end of which abuts on the curved disc.
Claim 4
Dependent Claim
77 words
A machine according to claim 2 and comprising a hydraulic system for controlling the movement of the advancing means and including an accumulator, characterized by hydraulic coupling means which during the reverse movement of the advancing means connect the pump with the accumulator and with a hydraulic pump adjustment cylinder connected to the pump housing so as to swing the pump housing into the position in which the piston rod engages the outer end of the arm.
Claim 5
Dependent Claim
34 words
A machine according to claim 3, characterized in that the space behind the plunger of the hydraulic cylinder communicates with a second accumulator and through a relief valve with a reservoir for hydraulic fluid.
Claim 6
Dependent Claim
24 words
A machine according to claim 4, characterized by a valve which on being activated establishes communication between the two ends of the hydraulic cylinder.
