ABSTRACT:
The drive mechanism for a reciprocating sub-mechanism on a weaving machine, e.g. for a cam for raising a projectile into the picking line, comprises a dead-center type crank drive. The drive is pivoted to and fro continually through 180.degree.. The connecting rod, which drives the projectile raise cam, is kept practically completely in the standstill position in the two crank standstill positions. This rod is mounted on an eccentric section of the crank pin so that small reciprocating movements of the crank in the dead-center positions due to play in the parts driving them cannot be transmitted to the connecting rod and projectile raise cam. The eccentric section of the crank pin can also be adjusted.
