cover backup pad and roll cover affixed thereto is that the roll cover backup pad and roll cover connection means sometimes causes a resultant protrusion either inward or outward of the cylinder cover assembly which protrusion frequently results in otherwise unnecessary wear and damage to the cylinder face in the case of an inward protrusion or in the case of an outward protrusion results in excess wear and damage to the steam chest apron as well as the steam chests in addition to impressing undesirable marks upon work pieces during the ironing operation breaking buttons on garment work pieces and other harmful effects the modified connection assembly 50 herein described provides a means to overcome the otherwise undesirable consequences resultant from either an inward or outward protusion in the cylinder cover assembly which result from the connection means thereof the modified connection assembly 50 is assembled generally as previously described i e the respective ends of the pneumatic roll cover backup member 36 and in the modified connection assembly embodiment one end of the roll cover member 38 are installed circumferentially around the longitudinal dimension of an ironing machine roll drum 26 when said pneumatic roll cover backup member 36 is in a deflated state by means of inserting pin members 40 through respective intermeshed knuckle members 44 of closely spaced belt lacing gudgeon elements 42 respectively affixed to integrally formed non pneumatic connection extensions 52 on said backup pad member 36 as respectively illustrated in fig8 10 it will be noted that the modified connection assembly members are generally internal of the lateral dimension of the pneumatic roll cover backup member 36 when said backup member is in the inflated operational state it will be further noted that a pneumatic extension.
