RECOMMENDATIONS
Before use the wire must be stored in dry, ventilated rooms with low humidity and without sudden changes in temperature to prevent rusting due to moisture condensation.
Before unwinding the wire in the coils, you must first release the coil from the bindings. This must be done carefully, especially when removing the end of the knitting wire threaded through a coil to prevent pulling out and entangling the turns of wire.
Then release the upper end of the wire threaded through the upper turns around the entire circumference of the coil. Before installing and threading the wire into the machine, make sure that the wire is not interwoven with adjacent turns. To do this, it is necessary to lift the end and several turns of wire and then put one turn back into the coil, making sure that there is no “overlapping” of the turns. This will prevent entanglement and wire breakage during the unwinding process.
Before unwinding coils of Z-2 or coils of another type, it is necessary to assemble the coils into a special detachable reel or other unwinding device, tightly fix the cheeks of the coil, ensuring maximum pressure against the wire to prevent “tightening” of the wire between the coils and the cheek of the unwinding device, which can lead to a break wire during unwinding and only after that release the coil from packing metal tapes. After that, tighten the coil or other device again for maximum clamping of the wire coil. Find and free the end of the wire, making sure that there is no “overlap” of the wire through adjacent turns. This will eliminate wire breaks during unwinding.
Each spool is wrapped with waxed paper, which is attached with twine; packed spools are stacked on a wooden pallet measuring (1070x815) mm. When packing the spools, the pallet is pre-lined with plastic wrap, a sheet of cardboard and a cardboard layer is laid between each row of spools. The spools laid out on a pallet are tied with a metal tape (0.5x16) mm, covered with a plastic film on top and wrapped with “stretch” film.
