Loading mechanism for the upper rolls of a drafting mechanism

A loading mechanism for use in a textile machine drafting zone for applying force to upper drafting rolls in the drafting zone, said loading mechanism comprising:

• a loading arm disposable above bearing arrangements for the upper drafting rolls in the drafting zone, said loading arm further comprising a cylinder holder;
• a pressurizable cylinder carried within said cylinder holder and variably positionable therealong, said cylinder defining a cylinder space attachable to a source of pressurized medium, and further comprising a piston rod moved by the pressurized medium;
• a securement device operably configured with said holder and said cylinder to releasably secure said cylinder at a desired position along said holder, and whereby upon release of said securement device, said cylinder is positionable along said holder to a different desired position;
• wherein said cylinder further defines a generally vertical guide surface defined on an outer surface thereof, said guide surface bearing against said holder and allowing said cylinder to be variably positioned along said holder;
• a stop plate defined on said holder against which said cylinder bears, said stop plate defined in a plane generally perpendicular to said vertical guide surface;
• and
• further comprising a retaining member attachable to said holder by said securement device, said cylinder disposed between said stop plate and said retaining member within said holder.

• and
• further comprising a cleaning lip device configured on said cylinder so as to contract the upper drafting roll upon positioning of said cylinder along said holder.

• and
• further comprising an electrical cut-off device configured with said cylinder, said cut-off device interrupting electrical power to the textile machine upon a condition sensed by said cylinder.
