Definitions

  • the present invention aims to provide users with a simple and inexpensive means for automatically cutting, under the control of a programmable table calculator for example, according to a chosen design, a sheet adhering to a support.
  • the present invention comprises a method according to claim 1, and an apparatus for carrying out this method, which is according to claim 2.
  • the device shown comprises an outer body 1, made of plastic, and an inner body 2, metallic, of generally cylindrical shape and axially pierced with a hole 3 which ends in 4 by a conical widening 4, at the place of the end 5 of the body 2.
  • a clamp comprising a cylindrical part 6 capable of sliding axially in the hole 3, and a slotted part to form four arms 7 (fig. 3) which, at their free end, have a conical part 8 provided for cooperate, as will be seen below, with the cone 4 of the body 2 ..
  • the interior of the split part 7 of the clamp 6,7 forms an axial cylindrical channel 14 into which a cylindrical part 16 of a knife holder 15 can slide.
  • a cylindrical part 17 of the knife holder 15 is located at the outside of the body 2, beyond its end 5. The diameter of the part 17 is greater than that of the part 16 and of the channel 14.
  • a shoulder 18 provided to abut against the free end of the arms 7 of the clamp 6,7, in order to fix the axial position of the knife holder 15 in the clamp 6,7.
  • the knife holder 15 has four longitudinal slots 19, in its region which is close to the free end of the arms 7 of the clamp 6.7 (when the members are in the position shown in FIG. 2, which is the working position of the device).
  • the knife holder 15 In its part 16, the knife holder 15 is axially threaded. A micrometric adjustment screw 20 is engaged in this internal thread.
  • the knife holder 15 is reintroduced into the pliers 6,7, taking care that the shoulder 18 abuts against the end of the arms 7.
  • the button 12 is turned to bring the conical end of the arms 7 of pliers in contact with cone 4, and tightened by turning.
  • the arms 7 then flex and act radially on the slotted part of the knife holder 15, which in turn flexes and energetically clamps the part 22 of the knife, which immobilizes the latter in the knife holder 6,7 and the latter by relation to the body 1,2. Simultaneously, the clamp and the body of the device are secured.
  • the sheet 27 is detached from its support 29 and the parts of this sheet foreign to cutting, are removed by tearing along the groove. Given the very small diameter of the active part of the tip 25 and the very small thickness of the part to be torn, the result is a clean cut practically equivalent to that obtained with a conventional cutting knife.
  • the shape of revolution of the knife-shaped point 25 makes it possible to cut all the possible shapes without difficulty: curves, sharp angles, etc.
