PosiClean®
 

PosiClean® is a line of easy to clean urethane food processing belting designed with sealed tension members and drive teeth across the full belt width. The belt can be cleaned-in-place with resulting savings in water, labor and waste water disposal when compared to plastic modular belting. The tension members eliminate belt stretch, a common cause of belt failure in long length applications.

Urethane Belt Load vs. Stretch Comparison

  • PosiClean can take up to four times the load of unsupported "blue" belts
  • Extremely length stable, eliminating the need for retensioning

Fastening Options

Belt Welding

The ability to thermally weld two prepared belt ends together allows for a seamless finish that minimizes bacteria growth and is easy to clean.

Welding Options:

Factory Weld – uses a 20 mm x 70 mm tapered finger to achieve the highest maximum allowable belt tension per inch

• 51 lbs/in for hi-torque PC20

• 39 lbs/in for standard PC20

Finger Splice

Field Weld – uses a straight cut belt end to achieve a maximum allowable tension of 31 lbs/in that is satisfactory for light and medium duty applications.

 
 

PosiLace™
This pin fastened method meets low to medium load requirements without welding to achieve the maximum allowable tension of 26 lbs/in.

Belt ends are prepared at the factory and the belt is joined by a single pin inserted after the belt is placed in position on the equipment.

This “living” fastening solution allows for removal and replacement of the belt as often as desired – without ever having to weld.

PosiLace Pin Fastening

Other Mechanical Fasteners
From wire hooks to metal staples, standard conveyor fasteners are available when contamination is not an issue.
