Detailed Description of the Invention The cardboard baler shown in FIG 1 is a mobile upright metal rack 10 with a cardboard compacting mechanism 20, and a rope tightening mechanism 30.
The rack 10 is an upright metal structure that is delimited by one inclined plane 11 and three vertical planes. The three vertical planes are made up of the left plane 12, right plane 13, and rear side plane 14. Located under base 70, the rack 10, there are four wheels 16.
The inclined plane 11 is bounded by two slotted steel channels 22 parallel to each other. The slots 23 of the channels 22 face each other.
Located on the upper end of the rack 10 and perpendicular to the inclined plane 11, is the compacting bearing plane 25. On the rearward side of the rack 10, opposite from the inclined plane 11 and on opposite sides of the rack 10, a pair of generally upright members 71 extend from the base 70 to connect respectively with the upper ends of the respective parallel channels 22, each at a respective upper apex 72. A pair of longitudinal members 73 extend respectively on each side of the rack 10 between one of the generally upright members 71 and the corresponding parallel channe122 connected to such one generally upright member 71, bracing the rack 10 and extending further outwardly from the inclined plane 11 to define and support the compacting bearing plane 25. Under this fixed compacting bearing plane 25 and perpendicular to the inclined plane, is the movable compacting platform 26. Four sliding pins 27 located on the movable compacting platform 26 slide in the slots 23 of the parallel channels 22 guiding the compacting platform 26 as it moves up and down.
A commercially available winch 21 is located at the upper top of the rack 10 at the upper end of the rear side plane 14. The winch 21 and the movable compacting platform 26 are connected by a strap 28. The movable compacting platform 26 is pulled upwardly towards the compacting bearing plane 25 along the inclined plane 11 by the winch's 21 mechanical power and slides down by its own weight.

A rope toggle clamp 35 is mounted on each outer side of the compacting bearing plane 25. On one side of the rope toggle clamp 35 towards the rope retracting shaft 32, there is a rope hook pin 37. On the other side of the rope toggle clamp 35 away from the rope retracting shaft 32, there is a rope guide 38. At each end of the rope retracting shaft 32, there is a rope retracting roller 36 and a rope locking pin 39.
In the bailing process of the cardboard the operator places flattened loose cardboard 40 on the movable compacting platform 26. The operator then turns the handle of the winch 21 to retract the strap 28 pulling up the movable compacting platform 26. This causes the loose cardboard 40 to be formed into the compacted cardboard 50.
To bind the bundle of compacted cardboard 50, the operator uses a length of rope 60 and makes an end loop at the end of it. The operator places the end loop on the rope hook pin 37. The operator then winds the free end of the rope 60 clockwise in Figure 5 around loose cardboard 40, placing the rope 60 along the rope guide 38, and aligning the rope 60 with the rope toggle clamp 35. Then the operator winds the free rope end onto the rope locking pin 39 and screws down the rope locking pin 39 to hold the end of the rope 60 fast to the rope retracting roller 36.
The operator turns the handle of the rope retracting ratchet gear 31 tightening the rope 60 until the rope reaches optimum tightness. Then the operator clamps down the rope toggle clamp 35 to hold tight the retracted rope 60. The operator then releases the rope locking pin 39 and makes a knot by tying the loose end of the rope and the rope loop together while the rope 60 is held tight by the toggle clamp 35 (see Figure 5). The operator then turns the winch 21 handle to release strap 28 lowering the movable compacting platform 26. The operator then removes the tied compacted formed cardboard 50 from the baler completing the working cycle of the baler.
Conclusion The foregoing has constituted a description of specific embodiments showing how the invention may be applied and put into use. These embodiments are only exemplary.
The invention in its broadest and more specific aspects is further described and defined in the claims which now follow.
These claims, and the language used therein, are to be understood in terms of the variants of the invention which have been described. They are not to be restricted to such variants, but are to be read as covering the full scope of the invention as is implicit within the invention and the disclosure that has been provided herein.
In the bailing process of the cardboard the operator places flattened loose cardboard 40 on the movable compacting platform 26. The operator then turns the handle of the winch 21 to retract the strap 28 pulling up the movable compacting platform 26. This causes the loose cardboard 40 to be formed into the compacted cardboard 50.
To bind the bundle of compacted cardboard 50, the operator uses a length of rope 60 and makes an end loop at the end of it. The operator places the end loop on the rope hook pin 37. The operator then winds the free end of the rope 60 clockwise in Figure 5 around loose cardboard 40, placing the rope 60 along the rope guide 38, and aligning the rope 60 with the rope toggle clamp 35. Then the operator winds the free rope end onto the rope locking pin 39 and screws down the rope locking pin 39 to hold the end of the rope 60 fast to the rope retracting roller 36.
The operator turns the handle of the rope retracting ratchet gear 31 tightening the rope 60 until the rope reaches optimum tightness. Then the operator clamps down the rope toggle clamp 35 to hold tight the retracted rope 60. The operator then releases the rope locking pin 39 and makes a knot by tying the loose end of the rope and the rope loop together while the rope 60 is held tight by the toggle clamp 35 (see Figure 5). The operator then turns the winch 21 handle to release strap 28 lowering the movable compacting platform 26.
