Claim 1
Independent Claim
219 words
In an apparatus for processing flatwork such as sheets or the like, the combination comprising a heated ironing cylinder having a surface speed of up to about 150 feet per minute, continuous belt means for engaging a sheet or the like to be ironed, guide rolls positioned adjacent said heated cylinder and having axes of rotation substantially parallel with that of said heated cylinder and engaging said continuous belt means whereby said belt means overlie at least about 80 percent of the heated cylinder circumference and are positioned to urge a sheet or the like into contact with said 80 percent said cylinder circumference; an Upper reach portion of said continuous belt means having a portion extending from adjacent relationship with said cylinder surface and adapted to convey a sheet or the like leaving contact with said heated cylinder; folder means for a sheet or the like disposed adjacent said ironing cylinder having an input feed conveyor; said continuous belt means portion conveying a sheet or the like leaving contact with said ironing cylinder onto said feed conveyor; said conveyor moving at a faster speed than said continuous belt means portion whereby a slight tensioning effect is imparted to said sheet or the like tending to remove wrinkles therein as said sheet or the like moves onto said conveyor.

Claim 3
Dependent Claim
40 words
The apparatus of claim 1 in combination with a retractable compression roll which counterrotatably engages under compression a surface portion of said main ironing cylinder, and means imparting a greater surface speed to said compression roll than said ironing cylinder.
Claim 4
Dependent Claim
29 words
The laundry apparatus of claim 1 in combination with exhaust means for withdrawing atmosphere adjacent a surface portion of said ironing cylinder to a location spaced from said apparatus.
Claim 5
Dependent Claim
117 words
The apparatus of claim 1 in which said folder means employs feed and a folding station adapted to buckle-fold a moving sheet on said feed transversely to the direction of sheet movement; said folding station having retractable clamp means, a stationary platform against which the leading edge of a sheet or the like is clamped by said retractable clamp means while the remainder of the sheet is conveyed on said feed therebeneath, and compressed air means for forcing the leading edge of said sheet or the like from said platform with said clamp means in the retracted position whereby said leading edge will drop upon the trailing edge of said sheet while moving on said feed belts.
Claim 6
Dependent Claim
41 words
The apparatus of claim 1 in which said belt means comprises two sets of spaced conveyor belts moving at different speeds; the belt means including said upper reach portion comprising a portion of the faster set of said first belt means.
