Abstract
Abstract A device for taking off slices sawn from rod-shaped material, having a take-off member which includes a holder and a conical flexible member. Between the holder and the conical member an annular element supports the conical element at some distance from its edge. By means of a vacuum, the center of the conical member is moved towards the holder and the edge is moved towards the slice just before the slice has been sawn entirely, and the slice is held by means of the vacuum.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
133 words
A device for taking off slices sawn from rod-shaped material, including a take-off member for holding a sawn slice by means of a vacuum and then removing the slice, wherein the take-off member comprises a holder, a conical flexible member which has a central aperture and a distal edge, and a supporting element disposed between the holder and the conical member and supporting the conical member at a location spaced from said edge and forming a side wall of a chamber between the conical member and the holder; and the holder includes an aperture communicating with the chamber and adapted for connection to a vacuum, the vacuum producing a sub-ambient pressure in the chamber and thereby moving the center of the conical member towards the holder and the edge away from the holder.
Claim 2
Independent Claim
133 words
A device for taking off slices sawn from rod-shaped material, including a take-off member for holding a sawn slice by means of a vacuum and then removing the slice, wherein the take-off member comprises a holder, a conical flexible member which has a central aperture and a distal edge, and a supporting element disposed between the holder and the conical member and supporting the conical member at a location spaced from said edge and forming a side wall of a chamber between the conical member and the holder; and the holder includes an aperture communicating with the chamber and adapted for connection to a vacuum, the vacuum producing a sub-ambient pressure in the chamber and thereby moving the center of the conical member towards the holder and the edge away from the holder.
Claim 3
Dependent Claim
44 words
A device as claimed in claim 1, wherein the supporting element is an annular element, the holder comprises a tubular portion having a flange from which the annular supporting element extends, the cone having an annular projection which is secured to the supporting element.
Claim 4
Dependent Claim
29 words
A device as claimed in claim 1, comprising in addition an annular abutting member adjustably secured to the supporting element for adjusting a rest position of the cone edge.
