Winder splicing nip guard

摘要

A guard is mounted for rotation about the downstream drum of a winder having two spaced apart winder drums which support a paper roll. The guard has a D-shaped leading-edge which approaches the paper roll. The leading-edge is articulated so that if an operator's hand becomes wedged between the leading-edge and the paper roll, articulation on the leading-edge closes a switch which brings the winder to a stop. A hydraulic actuator extends between a lowermost radial edge of each sector shaped extension and a fixed support. Operation of the hydraulic actuator causes the guard to rotate about the axis of the downstream winder drum so as to be between an operator and the downstream side of the winder drum. The leading edge of the the guard is positioned to limit operator access to the nip formed between the paper roll and the downstream winder drum.
