Abstract
A method of forming a perforated cut line using a cutting plotter capable of accurately and rapidly forming a sheet with a perforated cut line along a cut line which is predetermined on a sheet and along which the sheet is to be cut. A cutter pressure at which a cutter is pressed onto the sheet is repeatedly reduced for a micro period of time at predetermined time intervals to form the sheet with a perforated cut line consisting of perforations and unperforated parts defined between the perforations in an intermittent manner.
Claims8
A method of forming a perforated cut line by a cutting plotter adapted to relatively move a pen cartridge in X and Y directions with respect to a sheet while contactedly pressing a cutter supported on the pen carriage onto the sheet at a predetermined cutter pressure in a manner to be vertically movable with respect to the sheet, comprising the steps of:
- repeatedly reducing said cutter pressure for a micro period of time at predetermined time intervals to form the sheet with a perforated cut line comprising perforations and unperforated parts defined between said perforations, wherein the reduction of said cutter pressure is carried out to such a degree that a groove of a given depth is caused to be formed on each of said unperforated parts.
An improved method of cutting a sheet of flexible material by moving a cutter against the sheet at a predetermined cutter pressure, comprising the steps of:
- positioning the cutter adjacent the sheet;
- causing a predetermined pressure to be exerted against the cutter sufficient to cut the sheet;
- relatively moving the cutter and the sheet along a predetermined cut line to form a pattern;
- and
- varying the amount of pressure to the cutter to provide a series of perforations along the cut line spaced by unperforated segments, wherein the amount of pressure variation applied to the cutter causes grooves to be formed in the unperforated segments, and the pattern does not prematurely separate from the sheet to cause problems.
An improved method of cutting a sheet of flexible material by moving a cutter against the sheet at a predetermined cutter pressure, comprising the steps of:
- positioning the cutter adjacent the sheet;
- causing a predetermined pressure to be exerted against the cutter sufficient to cut the sheet;
- relatively moving the cutter and the sheet along a predetermined cut line to form a pattern;
- and
- varying the amount of pressure to the cutter to provide a series of perforations along the cut line spaced by unperforated segments, whereby the pattern does not prematurely separate from the sheet to cause problems, wherein the amount of pressure variation applied to the cutter leaves the cutter in constant contact with the sheet as it moves along the cut line.
