Abstract
A device is provided for placing a valve on an aerosol can. The device comprises a rotatable wheel (1, 101) which has arcuate cut-outs (2, 102) which receive and carry the cans. An arcuate track (6, 106b) follows part of the periphery of the wheel and converges towards it, and along this track valves are pushed by dogs (7, 104), provided adjacent each cut-out (2, 102). Each valve thus travels in alignment with its respective can and approaches it until it is placed thereon.
