Abstract
A sheet holder for holding a sheet of paper and exposing an edge of the sheet, has a press for holding the paper sheet and exposing the edge, and a lever for operating the press. The lever is movable between a released position for placing of the edge of the paper sheet in the press and a holding position for operating the press. There is also an abutment for abutment by the edge of the paper sheet to position the edge relative to the press while the lever is in the released position. The abutment is associated with the lever for moving away from the edge of the paper sheet when the lever moves towards the holding position, thereby exposing the edge of the paper sheet.
Claims7
A sheet holder for holding a sheet of material and exposing an edge of the sheet of material, comprising:
- a holding mechanism for holding the sheet of material and exposing the edge of the sheet of material;
- an operator for operating the holding mechanism, the operator being movable between a released position for placing of the edge of the sheet of material in the holding mechanism and a holding position for operating the holding mechanism;
- and
- an abutment for abutment by the edge of the sheet of material to position the edge relative to the holding mechanism while the operator is in the released position, the abutment being associated with the operator for moving away from the edge of the sheet when the operator moves towards the holding position, thereby exposing the edge of the sheet of material, wherein
- the operator is supported above the holding mechanism for pivotal movement between the released position and the holding position on opposite sides of the holding mechanism, and
- the operator has an edge portion, which is the abutment and which, in the released position of the operator, extends downwards for abutment by the edge of the sheet of material.
An edge pattern making apparatus for making a pattern along an edge of a sheet of material, comprising:
- a sheet holder having a holding mechanism for holding the sheet of material and exposing an edge of the sheet of material, and an operator for operating the holding mechanism, the operator being movable between a released position for placing of the edge of the sheet of material in the holding mechanism and a holding position for operating the holding mechanism, the sheet holder having a wall along an exposed edge of the sheet and a series of locating formations located at a uniform interval along the wall;
- and
- an edge pattern maker for making a series of patterns along the exposed edge of the sheet of material through repeated operations, each operation making one pattern, the edge pattern maker having a part for alignment with the locating formations to locate the edge pattern maker successively along the wall of the sheet holder for the repeated operations, wherein the sheet holder includes an abutment for abutment by the edge of the sheet of material to position the edge relative to the holding mechanism while the operator is in the released position, the abutment being associated with the operator for moving away from the edge of the sheet of material when the operator moves towards the holding position, thereby exposing the edge of the sheet of material, wherein
- the operator is supported above the holding mechanism for pivotal movement between the released position and the holding position on opposite sides of the holding mechanism, and
- the operator has an edge portion, which is the abutment and which, in the released position of the operator, extends downwards for abutment by the edge of the sheet of material.
