Claims
- 1. A fiber bale wire hooping apparatus for surrounding a fiber bale in a baling press with a metal wire the ends of which are held together by a crimped metal sleeve, comprising a strapping mechanism including wire supply means (16) having wire feeding and tensioning means (17, 25) for supplying lengths of wire, wire guide means (21, 31, 41, 44) forming a guide channel along at least three sides around said fiber bale for guiding a length of wire around said fiber bale, wire end holding means (22) at an end of said guide channel for temporarily holding a forward free end of a wire, wire clamping and bending means (20) arranged downstream of said wire feeding and clamping means (17, 25) as viewed in a wire feed advance direction from said wire supply means (16) to said holding means, wire cutting means (18) arranged downstream of said feeding and tensioning means (17, 25) and upstream of said wire clamping and bending means (20) for cutting a wire after a wire has been first tensioned by said feeding and tensioning means (17, 25) and then clamped by said clamping and bending means (20), means (51) for automatically applying a metal sleeve (6) onto a cut end of a wire, means (19, 36, 35) for tilting said clamping and bending means (20) holding a wire end with a sleeve on said wire end toward said holding means (22), whereby a wire end protruding from said holding means is also inserted into said sleeve alongside said cut wire end, and means (70, 71) arranged for crimping said sleeve for tightly securing said wire ends to each other.
- 2. The apparatus of claim 1, comprising a first carriage, a first plurality of said strapping mechanisms and a first plurality of said guide means arranged for cooperation with each other on said first carriage means for tying wire hoops around said fiber bale in a first direction, a second carriage, a second plurality of said strapping mechanisms carried by said second carriage, a second plurality of said guide means carried on said first carriage in a position for cooperation with said second plurality of said strapping mechanisms on said second carriage for tying further wire hoops around said fiber bale in a second direction extending substantially at right angles to said first direction, (FIG. 5).
- 3. The apparatus of claim 1, wherein said wire supply means comprise driven roller means (25) for driving a wire in a feed advance direction and means for reversing the rotational direction of said roller means for tensioning said wire when a forward free end of said wire is held by said holding means (22).
- 4. The apparatus of claim 3, wherein said wire guide means comprise wire gaps which are open toward said fiber bale, and wherein said tensioning of said wire pulls a wire through said gap against said fiber bale.
- 5. The apparatus of claim 1, wherein said means for tilting said clamping and bending means (20) comprise a displaceable tilting axis (73) for simultaneously tilting and displacing said clamping and bending means (20) to further maintain the tension in the wire as the sleeve is being crimped.
- 6. The apparatus of claim 1, wherein said holding means (22) and said clamping and bending means each comprise a plurality of clamping disks (56) and a common journal axis (55), said disks (56) being arranged in a row on said common journal axis, each disk having a cut-out (60) on one side of said journal axis (55) for forming a wire clamping jaw (61) and a cam follower on the other side of said journal axis (55), a common cam shaft (58) with one cam (59) for each of said disks arranged for driving said disks between a jaw opening position and a jaw closing position, and means connected to said cam shaft for driving said cam shaft.
- 7. A fiber bale wire hooping apparatus for surrounding a fiber bale in a baling press with a metal wire the ends of which are held together by a crimped metal sleeve, comprising first and second carriage means movable relative to said baling press, a first plurality of strapping mechanisms on said first carriage means, a first corresponding plurality of guide means on said first carriage means arranged for cooperation with said first plurality of strapping mechanisms for tying wire hoops around said fiber bale in a first direction, a second plurality of guide means on said first carriage arranged substantially at right angles to said first plurality of guide means, a second plurality of strapping mechanisms arranged on said second carriage means for cooperation with said second plurality of guide means on said first carriage means for tying wire hoops around said fiber bale in a second direction extending substantially at right angles to said first direction, (FIG. 5).
