PR-6 CLOSED-END PINCH ROLLERS
A 4' x 8' panel is rolled in 22 seconds instead of the customary 7-8 minutes experienced in hand rolling.
No quality control problems with callbacks due to poor, uneven laminating pressure - a superior, more uniform bond.
Cost justified with a value price: often the labor and material savings of one job or the avoidance of one delamination / product rework / warranty call can pay for the machine.
1500 lbs. of line pressure is more than adequate for normal laminating operations
Note that the top roll in this size is 1-1/2" longer on one end than the bottom roll to accommodate a raised edge: e.g. the top roller is 53" long and the bottom roller is 51.5" long. This will allow a standard depth clearance of up to 2" of build up on that end (see inset photo - previous page)
27 FPM roll speed, standard 3" openingfor material thickness, top of bottom roll is 33-1/4" from floor (pass height). Adjust this measurement if you add casters to predrilled machine pads
Standard roll material is 60 durometer neoprene with matte' finish (other coverings and/or durometers quoted on request)
Since you set your top roller to a specific opening for a particular laminating operation, you don't experience fractured laminate on the leading edge when it overhangs the substrate while forcing open pneumatically operated rollers. With our opening mechanism you avoid having to compensate for this problem by using less pressure than you want in a pneumatic system or requiring an employee to remember toincrease the pressure once the work has been fed. In addition, our crank mechanism remains consistent over its long operating life while one of the cylinders in a pneumatic system may eventually have a different output pressure which would result in uneven surface pressure.
VERSATILITY: Mar-Bel pinch rollers have been used for putting clear on aerial overlays, foil on styrofoam pontoons, the manufacture of computer flooring, boat manufacturing and a host of other applications in addition to the cabinetmaking and casegood / store fixture industries.
Electric motor brake for instant stops - Activated by gate movement or Red mushroom emergency stop button
Safety gates with interrupt circuit that must be reset if the gate switch is activated by the operator (we have latched - not momentary - circuitry). Gates move up and down with top roll as the roll opening is adjusted. Bottom guards in safety red are standard
