A cloth web preshrinking apparatus is disclosed including an inlet roller, a heated drum and a blanket (usually a felt type endless blanket) running on the inlet roller and then onto an outer face of the drum. A first initial outer surface of the blanket is stretched and then compacted. A cloth web is introduced into frictional contact onto the first surface of the blanket as it is stretched and the cloth web is then preshrunk as the first surface is compacted. A smooth strong flexible sheet of Teflon coated resin bonded glass fiber material (in the form of an apron or endless ribbon at least as wide as the cloth web) presses the cloth web onto the inlet roller and thereafter the sheet extends in contact with the cloth web on an upper face thereof onto the outer face of the drum. |
