B.GLS- Tube Machine is successfully researched, designed and manufactured by us with the advanced technologies home and abroad on our tube machine of the second generation. the B Compared with the machines of the same kind home and abroad, it boasts of lower investment, higher productivity, lower consumption, easier operation, automatic warning on failures, non-stopping roll re-feeding, accurate position of rotary cutting, easier maintenance and more stable performance. With the high frequency welding and the aluminium-plastic laminated material, it can produce laminated tubes of all specifications with smooth and firm welded seam. Its accurate cutting makes the tubes the same length. It can be combined with our B·T-III automatic shoulder-injecting machine to become an automatic tube production line that is scientific and reasonable in working in high speed and producing well products. It has the advantages of high utilization , lower labour intensity, more safety, etc. over the domestic tube machines used now. This machine is mainly composed of automatic roll-releasing device, connecting platform, storing case, automatic margin-cutting mechanism, automatic tube-forming device, high frequency welding mechanism, vertical and level traction devices, automatic tube-feeding mechanism, automatic synchronous revelling cutting mechanism and computer control system. It has awarded the national patent, and the patent number is 02219950.0. And the patent number of its high frequency welding device is 002119963.7.
