ABSTRACT:
A breathable girth former for a packaging machine for bathroom tissue and kitchen toweling rolls wherein the entrance funnel (preformer) has two halves resiliently mounted to conform to the product dimension most likely to jam in the downstream girth former. The funnel halves movement is transmitted to the girth tube former halves by a mechanical linkage to provide the same spacing as in the funnel.
