Features:

• Takes rollers cut to length, produces bag-ready rollers using multiple finishing stations.  Eliminates need to deal with paint roller tubes
• 1.5” diameter roller mandrels, can finish 3”, 4”, and 9” rollers
• Machine is magazine-fed
• Capable of finishing mini rollers and jumbo mini rollers with finishing station modifications and smaller-diameter mandrels
• Can change / calibrate each finishing station as needed to meet needed finish requirements
• PLC-controlled with touchscreen, field-programmable
• Finishes about 1,000 rollers / hour  

• Loading:
• Rollers are loaded into a vertically-oriented magazine which deposits rollers onto a loading trough. 
• The trough then uses an adjustable pneumatic arm to load rollers of any size onto finishing machine mandrels.
• Trimming:
• The trimmer station has spring-loaded arms with zirconia ceramic slotted blades that shave any excess material off both sides of the roller core.  The roller is actively spun while the trimming arms are engaged. 
• Trimming arms are equipped with a digital readout and threaded rod assembly for precise positioning.  Blades can be changed without tools, and blade holder angles can be set for any desired amount of shaving.
• Spin:
• The high-speed spin station spins rollers at 7,000 RPM. This removes lint and makes roller fibers stand up straight for carding and beveling operations.
• The station is made possible by our single-roller indexing form factor, and achieves lint removal well in excess of what’s possible through carding alone.
• Carding:
• Unlike buffers that use slow, actively-driven carding cloth drums, we use a carder mounted on a passive mandrel, while the mandrel the paint roller is mounted on actively spins.  This results in a higher-speed (2,000-4,000 RPM) carding treatment which removes much less fabric than traditional carding solutions, reducing waste as well as the need for carder maintenance. 
• Carder penetration depth can be precisely controlled via a handwheel.
• Beveling:
• We use lightweight beveling heads that have three degrees of freedom (towards / away from roller, up / down, rotating on an axis perpendicular to the roller) to provide precise beveler head positioning for all paint roller fabrics. 
• We make use of flexible shafts to mount the beveling head motors away from the beveling units, making the units much easier to adjust.
• The solid carbide end mills and hardened beveling blades can be easily adjusted and replaced as needed.  Combined with an actively-spun mandrel, the beveling units produce sharp, consistent edges. 
• Unloading:
• Finished rollers are ejected from the mandrel using a pneumatic arm. The rollers can be deposited into a conveyor or container.

NOTE: We were about to ship this machine to Sherwin-Williams, when they decided they didn’t want it.
