Abstract

An air current is caused to sweep through the chamber beneath a carding machine from one end to the other by means of a suction plenum beneath the lickerin end of the machine and an air inlet beneath the doffer end of the machine through which air enters and is conveyed toward the suction plenum. One or more baffles extending across the width of the area beneath the carding elements extend down in close proximity to the floor causing the air to pass closely adjacent the floor, rather than to drift up into the upper areas of the chamber. One of the aforementioned baffles is adjustably positioned in air deflecting arrangement with the aforementioned inlet to divert the incoming air currents immediately to the floor. The suction plenum is so connected with a source of negative pressure as to cause an air flow rate of at least 360 cfm through the inlet to the suction plenum. This combination causes such air currents to be guided downwardly beneath the lower edge of the inlet baffle and along the floor toward the suction plenum thereby creating a floor sweeping effect.
