Conventional Cams Single pass cams

With the conventional cam (figure 1) the turret is controlled by followers 1 and 2 at the start of indexing (position A).
Control is transferred to followers 2 and 3 before the end of indexing (position D) and, therefore follower 2 changes rotation between positions B and D, from maximum speed in one direction to maximum speed in the other, while follower 3 accelerates from rest to maximum speed.
At high speeds followers 2 and/or 3 must skid severely under load.

With the twin-dwell cam (figure 3) control is transferred from followers 1 and 3 to followers 2 and 3 before indexing starts (position A).
The same followers maintain control throughout the indexing period without any change of rotation or loss of contact. Control is transferred to followers 2 and 4 at the end of index (position E) leaving follower 3 free to slow down in clearance during dwell. No skidding takes place under load.

Double pass cams

With the conventional cam (figure 2) the turret is controlled by followers 1 and 2 at the start of indexing (position A), and is transferred to followers 2 and 3 (position C), and to followers 3 and 4 (position D).
Followers 2 and 3 change rotation from maximum speed in one direction to maximum speed in the other: also followers 3 and 4 accelerate from rest to maximum speed. At high speeds followers 2,3 and/or 4 must skid severely under load.

With the twin-dwell cam (figure 4) control is trasferred from follower 1 and 3 to followers 2 and 3 before indexing starts (position A) and is transferred in turn to followers 2 and 4 (position C) and followers 3 and 4 (position D).
Control is trasferred to followers 3 and 5 at the end of index (position E) leaving follower 4 free to slow down in clearance during dwell. Skidding of follower 2 under load is eliminated and of followers 3 and 4 is reduced.
