Abstract: An aerodynamic forming hood is provided for supplying a substantially uniform distribution of fibers in a downward laminar airstream for the deposition of the fibers on one or more forming surfaces. The hood is formed by a rectangular housing having opposed elongated downwardly diverging side walls and short downwardly diverging end walls. The housing has a smaller rectangular open top end through which a supply of fibers is released in an airstream which enters into the housing. The forming surfaces are disposed at a larger bottom forming end of the housing. The side walls and end walls in the top part of the hood are provided with elongated horizontal apertures. Controllable suction boxes are connected to the apertures for the controlled evacuation of air and fibers through the slots to substantially eliminate the formation of air turbulence and hence boundary layer separation in the airstream inside the housing to obtain the said laminar airstream with a substantially uniform distribution of fibers therein.

Abstract: An apparatus for making a nonwoven web comprises a carding drum and a continuously movable, air-permeable collecting surface member, which is arranged to collect the fibers which have been discharged from the carding drum and are entrained by an entraining air stream, through a suction duct, which extends between the carding drum and the collecting surface member. Passages for supplying air to the suction duct are provided throughout a predetermined working width of the drum and disposed adjacent to the duct at leading and trailing boundaries thereof with respect to the direction of rotation of the carding drum. To improve the uniform separation of fibers from the carding drum, it is proposed to arrange worker roller to cooperate with the carding drum adjacent to the leading boundary of the duct, and an air supply passage for supplying a stream of air to be sucked through the throat of the gap between the carding drum and the worker roller is provided between the worker roller and the carding drum and terminates on that side of the worker roller which is remote from the suction duct.

Abstract: Significantly improved carding production capacity and materially lowered waste content in the resulting sliver is obtained by high-speed operation of the lickerin at a speed in the range of about 1400 to 2000 r.p.m. and related operation of the main cylinder at a speed such that the lickerin surface speed is in the order of 90% of the cylinder surface speed, with a stripper bar lickerin screen located specially below the lickerin.
