A material discharge unit for separating lightweight elements of substantial size, such as paper or card trimmings, from a conveying air stream has a perforate duct (10) in a housing (11), with a perforate bend (12) at a discharge end of the duct (10). A baffle causes the conveying air stream and elements to impinge on an outside wall of the bend (12) at an acute angle. The trimmings are carried around the bend to discharge at C, while the air stream continues onward out of the housing (11) at B. The improvement resides in providing a mechanism (25) for adjusting the baffle plate angle while the unit is in operation. Also, readily openable panels (16, 18) are provided in the underside of the duct (10) and housing (11) to facilitate cleaning. |
