    摘要: The invention concerns a hydrophilic cotton fleece made by a method of manufacture characterized in that during the operations of boiling and bleaching in an autoclave, treatment liquids are made to circulate radially through the turns of a coil in such a manner that a differential pressure is established between the liquid entering the coil and a liquid leaving the coil as a result of load losses due to the difficulty which the liquid experiences in passing through the coil, the resulting cotton fleece exhibiting improved cohesion, resistance to tearing and absorption properties.

    摘要: An improved apparatus for cutting out discs from a sheet of cotton or other flexible material employs a reciprocating punch assembly having a punch whose stem is held in a housing that aligns the punch with an aperture in a die. The punch carries a protruding spherical segment that presses the interposed sheet material against the rim of the aperture in the die. To adjust for misalignment of the punch with the die aperture, the punch is resiliently supported in the housing in a manner permitting the punch sufficient movement to enable its spherical segment to enter the die aperture and force the flexible material against the entire circumference of that aperture in one stroke of the punch assembly.
