FLOW-TURN's Square-Turn curved belt conveyors use a series of cylindrical end rollers ("pucks") to replace the tapered end rollers of conventional powered belt curves.
Square-turn belt curves have a parallel belt-to-belt transition to and from adjacent conveyors. Conventional curved belt curves have tapered end rollers with a variable trapezoidal gap at the transfer point.
The cylindrical end roller design also has the advantage that the splice of the curved belt approaches the end rollers at a slight angle, which reduces noise and is additionally assisted in this by the plastic end rollers.
Square-turn belt curves do not have uneven gaps that can lead to unsafe hazard locations that must be covered with transfer plates.
The drive shaft of the belt curve is absolutely parallel to the shaft of the adjacent conveyor - in the case of conical rollers, the shafts are at an angle. This avoids interference between the drives mounted on the inside curve, and the motors are parallel and perpendicular as on a straight belt conveyor.
FLOW-TURNS pucks are the same size regardless of curve radius or belt width.
Belt curves with tapered rollers require a different roller for each variation of radius or width. For large installations, the savings on spare parts are important.
Square-Turn belt curves are available in a variety of sizes, curves and design options.
Standard puck diameters are (101.6 mm, 63.5 mm or 50.8 mm) depending on curve size.
The loose belt construction with chain driven belt has been in use for over 50 years and uses no friction drive between belt and drum to drive the belt and is therefore very gentle on the curved belt and the drums.
We look forward to hearing from you.
