Abstract
A can filling apparatus receives a band of carded fibers from a carding machine and deposits it in a rotating storage can. The apparatus includes a head part arranged above a rotatable can and having a rotary plate driveable to execute a rotational movement. Two calender rolls journalled for rotation on at least substantially horizontal axes on the rotary plate deposit the fiber band in continuous cycloidal loops into the can. At least one of the calender rolls is driveable by a friction wheel which is rotatably journalled on the rotary plate and runs around a fixed ring surface of the head part. An imaginary axis about which the friction wheel turns is arranged fixed in space relative to the rotary plate and the friction wheel has a conical surface which rolls off on a complementary conical ring surface of a window ring. The friction wheel can be adjusted or biased in the direction of the imaginary axis into engagement with the window ring and drives the calender roller associated with the friction wheel directly or via a shaft representing the rotational axle of the calender roller, optionally via a conical wheel arranged between the friction wheel and the shaft or between the friction wheel and the calender roller.
