ABSTRACT:
A prepackaged coiler assembly is disclosed and includes a housing, a plurality of wrapper rolls, a support for each of the wrapper rolls movably mounted on the housing, and motive hold-downs coupled to each of the supports and mounted on the housing. The motive hold-downs are disposed for urging the supports and the rolls toward a mandrel mounted independently and centrally of the wrapper rolls and for withdrawing the supports and rolls from the mandrel and from a strip coil thereon to permit ejection of the coil through a side opening in the housing. At least one of the motive hold-downs is disposed for withdrawing the associated wrapper roll and support to a further withdrawn position to permit lifting of the prepackaged assembly over the mandrel. The housing is provided with a bottom opening for passage of the mandrel therethrough.
