BLOCK & PAVER MACHINERY, MOLDS AND COMPONENTS

A survey of capital equipment suppliers to North American producers finds a trove of innovations and technologies supporting concrete block and paver variety, quality and application or design potential.

RAMPF MOLDS | TOPROC IMPRINT
Technology suited to all types of block and paver machines gives producers the ability to imprint up to four sides of a masonry unit, with nearly endless texture possibilities. Interchangeable segments afford production flexibility and the option of multiple textures on the same block or hardscape unit.

The Toproc system is free of hydraulics and pneumatics or other limitations, gravity its only driver. Compared to a hydraulic or pneumatic system, it requires less space in the mold, potentially yielding more products per shift due to no loss of cycle time. Rampf engineers characterize Toproc as “the revolution that takes away your hesitations to utilize the full potential of side textures. An entirely mechanical system designed to streamline and simplify the production process.” — Rampf Molds Industries Inc., Hagerstown, Md., 443/562-3812; www.rampf.com

While the original Mold Inspection and Repair Station limited swiveling of the mold bottom only, the second generation MIRS allows for tilting the mold head into various positions. Mold parts can be swiveled by manually cranked special worm gear drives. Swivel gears can alternatively be driven by a cordless drill to ease the process for maintenance staff.

KBH: Hardscape machinery uptime relies on damage-free mold maintenance
One essential element of concrete hardscape unit plant output is maintenance of tools used, in particular molds. In the course of producers expanding paver and wall unit offerings, molds are becoming more and more sophisticated, and with that lead times for new or replacement molds grow. Thus, proper mold care and maintenance are in order.

Traditionally, stripping the mold head from the bottom or base mold was done by using forklift trucks with chains or ropes. Setting aside the method’s questions of safety, the potential for damage arose during re-insertion of cleaned and inspected mold heads into bottom portions, but only after unit production resumed.

Hardscape unit machinery specialist KBH of Germany has addressed production line safety and maintenance cost factors with the Mold Inspection and Repair Station (MIRS). For cleaning and inspection, the complete mold is placed onto a receiving table by means of a forklift truck. The mold base is braced to the receiving table, while the head is braced to a lifting and lowering unit. After the head is drawn and clearly separated from the bottom, the latter can be swiveled into any direction for maintenance and repair. After cleaning and inspection, the mold base is moved back to a horizontal position for exact alignment with the head, which can be reinserted without damage to mold shoes and cavity walls.

“This device allows the machine operator to find a flawless mold after proper cleaning and maintenance, guaranteeing a smooth machine re-start after a mold change,” says KBH Sales Director Alwin Bennmann. “Well-known producers in Europe and North America very much appreciate the advantages of the MIRS, and are pleased about the improved mold service life and best possible availability of their hardscape machinery. The MIRS makes plant personnel’s job easy due to a prolonged mold lifetime and increased efficiency.” — KBH Maschinenbau, Lachen, Germany; www.k-b-h.de; North American market contact, Alwin Bennmann, 49 171 57 39 456, [email protected]
