Abstract: A planetary coiler for depositing a sliver in a stationary can comprising a rotary disc mounted on a stationary frame by way of a thrust bearing, a sliding supporting member slidably mounted on the inner side of the rotary disc, a coiler plate mounted on the supporting member, a calender roller mounted on the supporting member, and a turn plate provided with a sliver guide tube rotatably supported on the rotary disc, wherein any gap other than a small contact gap with the turn plate is not present so as to substantially prevent catching of sliver on the gap or intrusion of fibers into the gap. An annular gear is rotatably supported on the top surface of the rotary disc and centering of the annular gear is performed by the inner circumferential face of the rotary disc or the peripheral face of the annular gear.
