| 摘要 | An apparatus, or press, for removing the set from rolled welded wire fabric to permit laying the fabric as continuous flat unbroken strips. The apparatus includes a frame, or carriage, which supports a first yokelike assembly pivotally mounted on the frame for receiving, and preferably for lifting, a roll or welded wire fabric to an elevated position for unreeling. A second yokelike assembly, also pivotally mounted upon the frame, is provided with a pair of rolls through which the end of the wire fabric is passed. Sufficient stress or force is applied by the coupling action of the rolls to unset the distortion or set produced by the rolled condition of the welded wire fabric. | ||||||
| 权利要求 | 1. An apparatus for removing the set from rolled wire fabric to permit laying of the fabric as flat, unbroken, continuous strips comprising a frame, a first yokelike member pivotally attached at a position intermediate its extremities upon the said frame, one extremity of the said yokelike member providing a handle for application of leverage in elevating the opposite extremity of the yokelike member, the other extremity of the yokelike member branching into a pair of arms extendable upwardly from the frame when the said handle is moved downwardly, a transverse bar detachably mounted between the pair of arms of the said branched yokelike member, for receiving the roll of welded wire fabric, a second yokelike member, pivotally mounted upon the frame, provided with a separated pair of transverse rolls located between the branches formed by the said yokelike member, whereby welded rolled wire fabric can be placed upon the said transverse bar of the first yokelike member and elevated, unreeled from the roll, passed between the pair of rolls of the said second yokelike member, and force applied by the coupling action of the roll pair exerted in a direction which will remove the set caused by the rolled condition of the welded wire fabric. 2. The apparatus of claim 1 wherein locking means is provided for securing the said second yokelike member in position for application of force applied by the coupling action of the roll pair. 3. The apparatus of claim 1 wherein locking means is provided for securing the said first yokelike member in elevated position. 4. The apparatus of claim 1 wherein both the first and second yokelike members are provided with locking means for retaining the members in position. 5. The apparatus of claim 2 wherein the locking means of the second yokelike member includes two locking stations, a first wherein the pair of rolls are held in vertical position to facilitate insertion of the wire between the rOlls, and a second position for applying uniform force upon the wire unreeled from the roll. 6. The apparatus of claim 1 wherein the said first yokelike member is provided with fixed shields at the terminal end of and inside each of the branches, and receptacles opposite each for receiving the ends of the transverse bar. 7. The apparatus of claim 1 wherein the frame is provided with wheels to form a carriage. 8. The apparatus of claim 7 wherein the wheels which are provided are two in number. 9. The apparatus of claim 1 wherein the combination includes a bar for securing the wire ends of the unrolled wire, for applying uniform force thereto in unreeling the wire from the roll. |
