ABSTRACT:
A roller entry guide comprises a body with a pair of roller assemblies mounted on the body. The spacing between the assemblies is adjustable by a gear mechanism that induces relative longitudinal displacement between the body and the assemblies. Slides acting between the body and the assemblies produces a lateral component of movement to move the assemblies toward or away from each other while maintaining them parallel.
