摘要： A clothes dryer vent hood is fabricated of plastic by an injection molding process, and is provided with an integral rearwardly open annular portion for receiving a tubular member or pipe, which pipe is made of metal, and has several radially inwardly projecting tabs formed at the open end which is to be assembled with the annular portion of the vent hood. This annular portion is molded to define L-shaped grooves for receiving the tabs, and each groove has an abutment defined therein such that the hood can be assembled with the tubular member by axially joining these parts to move the tabs past these abutments in the grooves, followed by a twisting motion of the parts to further lock them together.

摘要： A machine for winding continuous tape and wire to form a flexible endless duct, which duct is fed out of the winding station by a cluster of rolls, and which rolls also serve as a mandrel at the winding station. The rolls are cantilever mounted with circumaxially spaced individual roll axes arranged in a hexagonal pattern around a central duct forming axis. The axes of the rolls are adjustable radially toward and away from the central axis, and these roll axes are also collectively adjustable angularly, that is to skew their collective axes relative to the duct central axis. The duct is marked off in units of length by a device which is periodically operated through a revolution counting circuit, and the duct is also cut by devices operated from a branch of said counting circuit.
