Abstract
An improved tensioning method, for tensioning the tying medium of a package tying machine, results from mounting a novel tensioning device on the tying machine's rotatable twine arm. The tensioning device utilizes a funneling structure to gather the tying medium, whether twine or tape or other material, into a prescribed volume while tensioning the same, thereby allowing a relatively high uniform tension value to be maintained in the tying medium throughout the package tying cycle.
Claims5
A method for establishing a substantially uniform tension in the tie material for a package tying machine, the method comprising:
- drawing the tie material along a support member;
- guiding the supported tie material through a constricted outlet member so as to gather the tie material into a uniform lateral dimension while in an untensioned state;
- flexibly compressing the gathered tie material into a uniform cross-section;
- and
- biasing the compressed tie material to thereby tension the same.
A method for use in establishing a uniform tie material tension in a package tying machine, the method comprising:
- supporting the tie material substantially at the tying machine's tensioner member;
- forcibly drawing the tie material along the tension member;
- gathering the drawn tie material into a uniform cross-section;
- and
- biasing the gathered tie material to thereby tension the same.
A method for use in the tensioner device in a package tying machine for establishing a substantially uniform tension in tie materials of the type capable of assuming various thickness dimensions depending upon the amount of twisting thereof, the method comprising:
- drawing the tie material into the tensioner device;
- and
- forming the tie material into a substantially uniform cross-section dimension at a point before the tie material engages the tying machine's tensioner biasing means.
