Abstract
A micro adjuster laterally moves a paper punch die. A modified fixed bracket with a larger fine-threaded hole is used to retain a hollow micro adjuster screw which is engaged by the fine threads of the bracket. The retaining screw that attaches to the die now does so by being inserted through the hollow body of the micro adjuster screw and out of a clearance hole at the distal end. Fine lateral adjustments of lateral alignment between the paper to be punched and the die can now be performed by moving the die laterally.
Claims17
A micro adjuster for a paper punch die having at least one punch pin capable of punching at least one hole in at least one sheet of paper, wherein said sheet of paper is guided by guides set on either side of the at least one sheet of paper, said guides guiding said at least one sheet of paper properly in a centrally aligned manner through the punching die to a predetermined punching position adjacent to said at least one punch pin, said micro adjuster comprising:
- a hollow threaded member laterally movable with respect to a corresponding fixed threaded member;
- said hollow threaded member engagable with the die;
- and,
- said hollow threaded member and the die laterally movable in unison to a predetermined position corresponding to said predetermined punching position at least one sheet of paper.
A laterally adjustable punch die in combination with a paper punch machine comprising:
- a paper punch machine including a punch die having a recess for insertion of multiple sheets of paper therein;
- said punch die having a movable punch portion with at least one punch pin punching at least one hole within said multiple sheets of paper;
- said multiple sheets of paper being retained in a position for punching of said at least one hole therein by a pair of side guides;
- said punch die being laterally movable with respect to a desired punching position against said multiple sheets of paper by a hollow threaded member having outer threads engagable with inner threads of a fixed bracket of said paper punch machine for laterally advancing and retracting said punch die with respect to said desired punching position;
- and,
- said hollow threaded member having a bore extending therethrough for insertion of an actuator wrench engaging a retainer fastener fixing said hollow threaded micro adjuster to said punch die.
A method of laterally moving a paper punch die with respect to a desired punching position against a positionally fixed plurality of sheets of paper to be punched by said paper punch die, comprising the steps of:
- threadably attaching a hollow threaded micro adjustment member to reciprocating threads of a fixed bracket of a paper punch machine holding said paper punch die;
- retaining said hollow micro adjustment member in engagement with fine threads of said fixed bracket;
- inserting a retaining screw attachable to said punch die through a hollow bore within said micro adjustment member and out of a clearance hole at a distal end therein;
- laterally adjusting said punch die to the desired punching position above the plurality of sheets of the paper to be punched;
- and,
- locking said punch die in place so that no more lateral movement of said punch die occurs.
