2.Haili is expert in producing various roll wheel, such as chrome-coating and tungsten carbide corrugated roll, metal and ceramic anilox roll, embossing roll, concave roll, mirror roll, printing roll, rubber roll, etc.
3.According to specific requirements, the thermoplastic sheet is embossed directly in a post-calender unit equipped with a device for quick change of the embossing roll.
4.In this thesis,the characteristics of ERW forming and calculating method of the strip deforming graph are researched,and the software for the automatic generation and analysis of the strip deformation graph is developed.
7.The 3-roll calender includes the em-bossing and the take-off and cooling units.
8.High-speed stripper can effectively wipe off returning flow of fibres and decrease stopping rate, thus protecting doffer card clothing.
9.In the article the action of mechanism of drafting cots with spiral grooves and the reasons for less lapping are analysed, the development of spiral grooves and application of drafting rollers with spiral grooves on E 74 and A 201 combers, A272 doubling machines and their popularization are portrayed.
10.Through the research and analysis of ERW forming,geometric and physical deformation data in the ERW forming process are obtained,which provide useful information and essential data for the design of ERW production line.
