Abstract
Abstract A pressing machine intended for covering fabric articles with a sheet coated at least partially with a thermally sensitive adhesive or for ironing fabrics includes an upper fixed platen and a lower movable platen. Two carriages are provided for introducing fabrics to be treated to the space between the platens, one being inoperative at any given time. The lower platen carries a flexible sheet member sealed at its periphery and capable of being inflated by compressed air, whereby the pressure on the articles is equalized over their whole surface area.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
104 words
A pressing machine, comprising; structure defining a fixed surface, an impermeable and deformable diaphragm member forming a pressing surface arranged to cooperate with the fixed surface, said diaphragm member defining at least in part a sealed chamber, means for moving the diaphragm member towards and away from said fixed surface, two carriages for interposing material to be pressed into the space between the surfaces, guideways supporting the carriages, means for inflating the diaphragm member to perform a pressing operation when the two surfaces are closely spaced from one another, and control means for rendering the moving means inoperative if the carriages are incorrectly positioned.
