The development of the first strip thickness gauge worldwide, that could measure the thickness of the strip during the rolling process in cold mills with an accuracy of µm, was the start of our company in 1963.

Automatic Roll Measurement
On-Line Measurement
Measuring the rolls during grinding offers the optimum chance to set the necessary close roll tolerances rapidly.
These fully automatic roll gauges are permanently installed on the roll grinder, measuring the roll profile, the roll diameter and the roll roundness during the grinding process. The transducers follow the track of the grinding stone / grinding wheel, providing the full information on the roll geometry at any time of grinding.
For the application in the paper industry, the 3-D measurement option (three-dimensional measurement and indication of the roll form) is a highly attractive addition. If the roll grinder has the function “3-D grinding”, an automatic correction grinding is also possible in the 3-D cycle.
For the application of the gauge on large rolls that must be aligned in the roll grinder with some effort, an additional transducer is mounted on the carriage that measures the alignment of the roll to the grinder.
Correction Grinding
Many CNC controls on grinders afford a communication with the roll grinder control can be made and that data is used in an online correction grinding scheme.

VIP 08 Flatness Measurement System
While the strip thickness tolerances were a significant criterion for the quality assessment of strip material in the eighties and nineties, significant improvements in controls and automation have made good thickness control a given among suppliers.
First Isotope Thickness Gauge Application in Mexico
During this past fall, we installed our first two – Model A3000 Isotope Thickness Gauges in Mexico. The application was for stainless steel on a heavy-duty reversing mill with 24/7 operation.
Quality and Yield Optimization on Cold Rolling Mills
In order to accommodate for the high demand in accuracy, quality and yield, it is essential to optimize the existing operating equipment. In the past Vollmer has supplied and been known for their high performance thickness gauges in conjunction with the automation of the screwdown system.

BFI Article shows new design for shape roll measurement
The well-proven BFI version shape measurement roll has undergone a design change that improves its ability to measure the tensions profile on flat product without marking the strip. The detectors have been redesigned to fit into the roll while leaving the surface of the roll completely clear of machined marks. This eliminates the former problems associated with the axially installed sensors.
