Abstract

1,225,008. Controlling tension; feeding webs. 17 Oct., 1969 [18 Oct., 1968], No. 49573/68. Headings B8G and B8R. [Also in Division D1] Wire or paper tape 1 being unwound from the supply roll 2 is passed around a dancer roller 3 on a dancer arm 4 tensioned by a spring 5. The arm 4 is coupled to a brake belt 6 by a mechanical network comprising a tension spring 14 in parallel with an hydraulic damper 13. The spring 14 may be a tension spring (as shown), or a suitably arranged compression spring or leaf spring. The hydraulic damper 13 may be a rotary hydraulic damper coaxial with the axis 15. The mechanical network is stated to permit the tension control to be predicted mathematically to permit a substantially stable tension in the wire or paper 1.
