Abstract
A cam and follower system for use with an automatic doffing system of a rotor spinning machine. The system includes a cover member for covering the cam lobes of a cam gear found in the automatic doffing system of a rotor spinning machine. The system also includes a cam follower for connection to the automatic doffing system. The cover member has cam surfaces which are complimentary to and which act to renew the original cam surfaces of the cam gear's cam lobes. The cam follower is adapted to engage and ride upon the cover member's cam surfaces during operation of the automatic doffing system.
Claims17
A device for use with an automatic doffing system of a rotor spinning machine, the automatic doffing system having a cam member, the device including a cover member for covering a portion of the cam member, said cover member defining at least one cam profile, and said cam profile defining at least one cam surface.
A combination for use with an automatic doffing system of a rotor spinning machine, the automatic doffing system having a cam member defining cam surfaces, the combination including:
- a cover member for covering the cam surfaces of the cam member, said cover member defining cover member cam surfaces;
- and
- a cam follower for connection to the automatic doffing system, said cam follower being adapted to engage and ride upon said cover member surfaces during operation of the automatic doffing system.
A method for providing an automatic doffing system of a rotor spinning machine with cam surfaces, the automatic doffing system having a cam member and a follower, the method comprising:
- providing a cover member adapted for covering the cam member, said cover member defining cam surfaces thereon;
- and
- placing said cover member on the cam member such that said cam surfaces are exposed for contact by the follower.
