Abstract
Abstract An improved method is provided for wrapping generally cylindrical bales of hay with twine to maintain the structural integrity thereof, in which a unique pattern of twine bindings is utilized to achieve greater strength and reliability. A related form of improved bale wrapping apparatus is also provided, in which the electrically driven twine guiding tube is electrically controlled in manner to automatically produce the pattern of bindings contemplated by the method, and which requires operator attention or control only for initiating the otherwise automatic operating cycle. The method and apparatus significantly utilize time reference techniques correlated with the known rate of rotation of the bale to produce the improved pattern of bindings and to control the production thereof automatically.

Claim 1
Independent Claim
341 words
For use in combination with a baler machine for forming hay into a generally cylindrical bale of the type having means for supporting and rotating the bale and means for supplying and feeding a filament to be wrapped upon at least portions of the bale as the latter is rotated, improved means for controlling the application and pattern of filament wrapped upon the bale including: shiftable means for guiding a wrapping filament toward various locations along the axial dimension of a bale during rotation thereof, said guiding means having a first position adjacent one extremity of the bale and a second position adjacent the other extremity of the bale and being movable in either direction therebetween through a number of intermediate positions; drive means operably coupled with said guiding means for moving the latter in either direction when said drive means is operated in a corresponding direction; and control means operably coupled with said drive means and operable when actuated for causing said drive means to move said guiding means from said first position to said second position in a single continuous motion during a first predetermined period of time, then to automatically move said guiding means from said second position to said first position in a series of successive motions each of a second predetermined period of time separated by dwells each of a third predetermined period of time at each of a plurality of said intermediate positions, said control means including a main, manually operable actuator device adapted for initial manipulation and release by the operator of the baler machine to start a wrapping cycle consisting of one complete, reciprocatory movement of said guiding means to and from said first position, components responsive to said initial manipulation of the actuator device to actuate said drive means, and means coupled with said components for maintaining the same in a condition actuating said drive means in a manner to move said guide means through a complete wrapping cycle notwithstanding release of the actuator device by the operator throughout the wrapping cycle.
