Abstract
A corrugating machine finger setting jig is disclosed having an adjustable profile surface to simulate the arcuate profile of a cooperative corrugating roll.
Claims3
An assembly jig for corrugating machine finger-holder units comprising:
- A. a side plate and a base plate integrally joined in mutually perpendicular planes;
- B. a reference axis disposed perpendicularly to said side plate;
- C. holder mounting means on said base plate to locate and secure a finger holder in substantially the same spacial position relative to said reference axis as said holder would occupy when mounted on a subject corrugating machine;
- D. first adjustable surface means secured to said side plate at a radial distance from said reference axis approximately the same as a radius of a subject corrugating roll for locating one arcuate end of a stripper finger in substantially the same spacial position relative to said reference axis and holder mounting means as said one arcuate end would occupy on said subject corrugating machine;
- E. a plurality of second adjustable surface means secured to said side plate in an arcuate distribution relative to said reference axis for locating intermediate arcuate surface points on said stripper finger in substantially the same spacial positions relative to said reference axis and holder means as said intermediate points would occupy on said subject corrugating machine;
- and
- F. clamping means to temporarily secure said stripper finger to said side plate in simultaneous contact position with said adjustable surface means.

A method of presetting the positional relationship between a corrugating machine stripper finger and a holder therefor, said method comprising the steps of:
- A. securing a combined finger and holder unit to a subject corrugating machine finger mounting bar;
- B. adjusting the set relationship between said finger and said holder to a predetermined clearance between said finger and a corrugating roll of said machine to form a pattern unit;
- C. without disturbing said set relationship, removing said pattern unit from said mounting bar and securing same to a jig mount;
- D. setting a first adjustable surface of said jig mount to point contact with one arcuate end of said jig mounted pattern unit;
- E. setting a plurality of second adjustable surfaces of said jig mount to respective points of contact with an inside arcuate edge of said pattern unit finger;
- F. removing said pattern unit from said jig mount and substituting an unset finger and holder unit therefor;
- G. adjusting said unset finger to simultaneous point contact with said first and second adjustable surfaces;
- H. securing the set relationship between said unset finger and holder to form a preset finger and holder unit;
- and
- I. without disturbing said set relationship, removing said preset unit from said jig mount and securing same to said subject corrugating machine finger mounting bar.
