COMPOSITE JOINING BELT MATERIAL FOR REINFORCING STEEL BELT OF PLASTIC-STEEL WINDING TUBE

摘要

The composite joining belt material is used for reinforcing steel belt of plastic-steel winding tube. The belt material at least has a belt body which comprises a base plate (30) and at least one ribbed plate (40). The ribbed plate is arranged vertically to the base plate. There is a steel belt (401) in the ribbed plate. And the ribbed plate is jointed on the base plate. There is a joining part set on one side of the base plate. The joining part is smooth surface structure. And the joining part has one joining convex (32) at least. An occlude surface design make the joining between belt materials more steady and reliable, as well as ensure the welding strength and the quality of the tube.
