ABSTRACT:
An apparatus and method of handling flexible foldable materials, particularly thermoplastic film webs, continuously fed from a supply by continuously moving input nip rolls to a dancer including a roll mounted for movement transversely to its central axis. Intermittently moving draw rolls intermittently advance material from the dancer roll. The dancer roll is reciprocated in coordination with the intermittent advancement so as to decouple the translational inertia of the dancer roll from the material. A flexible belt also simultaneously rotates the dancer roll so as to decouple rotational inertia of the roll from the length of material. The dancer may be driven by a cam in common with a work station reciprocating against the material fed from the dancer.
