B2
Abstract:
Apparatus for inserting fibrous plugs into the ends of pipettes comprises means for successively severing lengths from a fibrous strand (usually cotton wool roving) the means having a knife edge, and a relatively movable roller arranged to roll along the knife edge and cut the strand. Preferably the fibrous strand is fed by increments vertically downwardly under gravity towards the severing means, so as to avoid the formation of fluff which occurs when pneumatic feeders are used.
