ABSTRACT:
An apparatus for bonding, without adhesive, a plastic material layer onto a backing fabric of any kind, wherein the fabric is biaxially stretched and untreated, includes a calendar and a rocking device. The calendar includes a heated cylinder for coating the fabric with a layer of plastic material. The rocking device includes a preliminary heating element, a front end roll, and a rear end roll. The front end roll and rear end roll guide the stretched fabric onto the heated cylinder of the calendar to control the heating temperature of the stretched fabric in contact with the heated cylinder. The preliminary heating element is interposed between the front end roll and the rear end roll.
