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.

Plastic cassette

Cassettes are packed in bags of heat-shrinkable plastic film sealed on four sides. Cassettes in bags are placed in a box of corrugated cardboard with a size of (1000x800x600) mm. Each row of cassettes is shifted by a sheet of three-layer cardboard (950 x 800) mm in size. The box is sealed with adhesive tape, installed on a wooden pallet with a size of (1100x950) mm and tied with a packaging polypropylene tape (0.9x19) mm. Silica gel bags are placed in plastic bags with cassettes

  • Type of winding:Plastic cassette
  • Dimensions, mm, d*D*h:52х200х50
  • Weight kg:5
  • Diameter range, mm:0,8 – 1,4
Metal cassette

Cassettes are packed in bags made of heat-shrinkable plastic film sealed on four sides and placed in boxes made of corrugated cardboard with a size of (310x310x105) mm. The boxes are sealed with adhesive tape and packaged on wooden pallets of size (990x990). Each pallet is lined with plastic wrap, a sheet of cardboard is placed on the film and then boxes are installed. Each row of boxes is shipped with corrugated cardboard. A cardboard sheet is placed on top of the boxes and covered with a film. Then the pallet with boxes is wrapped with “stretch” film and tied with polypropylene packaging tape (19x0.9) mm. In the places of linking the boxes, plastic corners are placed. Silica gel bags are placed in plastic bags with cassettes

  • Type of winding:Metal cassette
  • Dimensions, mm, d*D*h:180х300х100
  • Weight kg:15-18
  • Diameter range, mm:0,8 – 2,0
Coil

Each coil is tied with annealed wire in 4 places, evenly spaced around the circumference of the coil. Then the coils are packed on a packaging machine in a polypropylene fabric with the accompanying annealed wire. The overlap of the turns of the packaging tape is at least 50% of its width. The end of the polypropylene fabric is attached with adhesive tape.

Coil Z2

Each coil is tied with a metal steel tape (0.5x16) mm in at least six places evenly spaced around the coil. The coils are packed in a polypropylene fabric, tied around the circumference with tape and installed on wooden pallets of 2 coils (fixed to the pallet with packing tape (0.5x16) mm) or 3 coils (fixed to the pallet with metal tape (0.8x30) mm) in four places evenly spaced around the circumference. Pallet size is (730x730) mm. The pallet is lined with wrapping paper (cardboard). A corrugated cardboard is laid between the coils. When bundling 3 coils on a pallet, a wooden cross is installed inside the coils.
