Planetary napping machine

摘要

A planetary napping machine includes a napping roller drum assembly and cylinder head construction which facilitates assembly and servicing of the apparatus. The napping machine includes a frame and a napping roll drum assembly having a main shaft which is rotatably supported on the frame. One end of the main shaft engages with a drive assembly to drive rotation of the napping roll drum relative to the frame. The napping roll drum assembly includes spaced cylinder heads mounted on the main shaft, and napping rollers each having first and second ends which are respectively rotatably journaled in bearing assemblies which are circumferentially spaced around said first and second cylinder heads. The first ends of the napping rollers have extended end portions which extend through the bearing assemblies on the cylinder heads. The drum assembly still further includes drive motors respectively mounted on the cylinder heads. A belt pulley is carried on the terminal end portions of each of the napping rollers and a drive pulley is carried on the drive shaft of each of the napping roller drive shafts. Endless belts interwoven about the drive pulleys and belt pulleys on each end of the drum assembly drive rotation of the napping rollers relative to the cylinder heads. Each of the cylinder heads includes a cylindrical body portion and a plurality of bearing assemblies removably mounted about the circumference of the body portion.
