1 Band: Custom Injected Polyurethane With Patented Locking Looper.

2 The strategies of the looper height control and strip tension control of the specific mill are described.

3 After the parameters of the looper system and silicon control system were matched reasonably with each other, the non-tension rolling was realized.

4 Describing working principle and method of new hydraulic looper control system supplied by Germany.

5 According to the CSP process requirement, the looper control device and control system including its structure, function and auto-control principle is researched.

6 Being aimed at the fluctuation of the looper angle and the strip steel tension in the traditional looper control, the tension-weighted control and the state feedback control strategies were proposed.

7 This paper analyzed some problems of the looper system, such as bad stability and resistance to disturb, slow regulation.

8 Entry strip support table, looper roll and four-point centering device.

9 Looper system is an important part in steel rolling production-line, and faults of this system can effect the whole line's running and the product's quality.

10 Bend needle mechanism and looper mechanism are two important mechanisms in blind stitching machine.

11 The patented looper thread take-up put on the front of body, to clean the winding and adjustment easily.

12 Connecting rod feeding mechanism , needle bar basting, looper hooking form parallel chain - stitch, which stitch is firmelastic.

13 The patented looper thread take-up put on the outside of body, to clean the winding and adjustment easily.

14 The method is applied to the looper height and tension control of hot strip mill. Simulation result proves effectiveness of the method in both decoupling effect and control performance.

15 PLC control is adopted in automatic control system for finishing area of Chumiwei 950 mm hot strip mill Main functions include speed cascade control, tension control, looper control, APC control etc.

16 A kind of method adopting polynomial approaches to match the nonlinear curve of looper tension moment is put forward on the base of analyses of the curve characteristic and project practice.

17 The adjustment mechanism is inter-stand tension modifications through changing looper motor currents and angles .

18 The control strategy of prediction for a linear model based on BP-PID was introduced to improve control effect and to decouple the looper system.

19 Automatic velocity control system for the continuous tandem cold mill let the rolling mill work continuously by using the looper to keep the uncoiling operation separating from the rolling process.

20 DDRT-PCR technique was used to explore the differential gene expression profiles analysis of tea plant induced by tea looper (Ectropic oblique) attack.

21 Several methods for recovery procedure of the polyhedral inclusion bodies of nuclear polyhedrosis virus of the poplar looper, Apocheima cinerarius, were compared.

22 After that, the strip is passivated and dried. Then the strip goes into exit looper.
