ABSTRACT:
Pipets of virtually any size are delivered automatically and continuously with the assistance of gravity to an intermittent rotary transport mechanism which carries each pipet separately to a plugging station. At the plugging station, each pipet is engaged and held against movement while precut cotton plugs are inserted into the pipets by a reciprocating needle device controlled by a mechanism which simultaneously controls and coordinates the activity of scissor blades which sever a cotton roving during a dwell of a roving transport wheel on the shaft of the pipet rotary transport mechanism. After being plugged, each pipet is delivered from the rotary transport mechanism onto a collection apron. A multi-position stop element on the inclined pipet delivery rails of the machine allows pipets of varying diameters to be plugged with precision without requiring additional machine adjustments.
