Abstract
Apparatus for binding bales by winding a filament, such as a wire or similar device thereabout, is provided with a twisting head which operates to twist together the ends of a binding filament after the filament has been wound around a bale. As the twisting operation is performed, tensile forces developed in the twisted filament may cause rupture of the filament. To avoid such rupture, the twisting head is resiliently mounted to enable absorption of the filament tensile forces thereby to avoid undesired rupture of the filament.
Claims11
In apparatus for applying binding filaments about bales of material, said apparatus including press means for producing said bales, and binding means operating to apply about each bale at least one loop of a binding filament arranged to extend within a winding plane, said binding means including a twisting head for twisting together ends of said binding filament, said twisting head being moveably mounted upon said apparatus to be swung in and out of twisting position, the improvement comprising means resiliently mounting said twisting head when said head is in said twisting position, said resilient mounting means being arranged to enable movement of said twisting head in a direction generally toward said bale during the time that said twisting head is performing a twisting operation.
Apparatus for applying binding filaments about bales of material comprising means for forming bales to be bound and for moving said bales in a given direction, supply means for providing filament for binding said bales, said supply means being arranged to direct said filament to extend transversely across the front side of said bales forwardly thereof taken relative to said given direction, reciprocating means moveable transversely of said given direction behind said bales for gripping and winding said filament about the rear side of said bales in order to bring portions of said filament into general adjacent relationship with the length of said filament between said adjacent portions extending around said bale, twisting means for twisting said adjacent portions together, cutting means for cutting said twisted adjacent portions at a point intermediate said twist so that portions of said filament on both sides of said cut remain twisted together, and means for resiliently mounting said twisting means to absorb tensile forces developed in said filament during twisting of said adjacent portions thereof, said resilient mounting means being arranged to enable said twisting means to move in a direction generally toward said bale while said twisting means is performing a twisting operation.
