PCT No. PCT/GB91/01388 Sec. 371 Date May 7, 1993 Sec. 102(e) Date May 7, 1993 PCT Filed Aug. 15, 1991 PCT Pub. No. WO92/03362 PCT Pub. Date Mar. 5, 1992.An apparatus and method to control the velocity and spacing of a spaced feed of objects, includes a member rotatable about an axis and having at least one receptacle, the objects being fed into the apparatus in spaced succession so that they are captured in the receptacle and so that they acquire the circular motion of the member. The receptacle has means for releasing the objects so that they are projected with a predetermined velocity and with a predetermined frequency. The phase relationship of a rotatable feeder and the rotatable member is controlled by generating a signal representative of the phase difference of the rotatable members, filtering the signal for maintaining loop stability and controlling the drive means of the rotatable member using the signal. |
