ABSTRACT:
An apparatus for holding a textile bobbin on a support roller and for facilitating the exertion of a controlled bearing pressure from the textile bobbin against the support roller. The apparatus comprising a creel for grasping the textile bobbin, a shaft for supporting the creel for pivotable movement relative to the support roller, a lever mechanism for applying a variable torque to the creel as a function of pivoted movement of the lever mechanism, and an adjustment device for varying the torque applied to the creel via the lever mechanism. The adjustment device comprises a rotatable eccentric element disposed to act on the lever mechanism for establishing an adjustable base position of the lever mechanism according to a rotated position of the eccentric element.
