Private equity-backed Maxcess International Corp. is buying Valley Roller Co., which makes parts for manufacturing equipment.

The Appleton, Wisconsin-based target makes rolls and roll coverings for plants that make a range of products, from personal care items, to packaging to paper. Terms of the deal were not disclosed.

Maxcess, headquartered in Oklahoma City, provides products and services for manufacturers. The company owns the web guiding brands Webex, Fife, Tidland and Magpowr, which provide services that help manufacturers’ position flat materials.

Maxess is backed by San Mateo, California-based PE firm Bertram Capital, which bought it in December 2012. Under the firm’s ownership, Maxcess acquired Fives North American Combustion Inc.’s guiding systems business in December. That move, which added guiding technologies, was meant to help the business broaden product offerings and services. Maxcess came into the Bertram equation after in January 2014, Bertram-backed Webex bought Maxcess.  

Bertram has $850 million in capital under management and invests primarily in lower middle-market companies. For more on the firm, watch our video interview with Michelle Chao.
