The cloth iscarried by a series of rollers to the gas jets, and in passingover the rollers c, c, c, c the one side of the cloth impingeslaterally four times against the flame, which is nevfirpermitted to pass through the fabric, but only shaves itssurface. The back is thus singed in the first portion ofthe apparatus, and being turned over on roller d it iscarried forward to another pair of jets, where, beingthoroughly dry, the face side of the cloth is completelysinged by going over exactly the same course throughwhich the back is carried in the first part. By an arrange-ment not shown in the illustration, the attendant of themachine can instantaneously lower the gas burners by atreadle movement in case of any stoppage or accident, andthus prevent the cloth from being burned. With a properpressure of gas this machine singes
