GRAND RAPIDS, Mich. — Rowe International, manufacturer of bill changers headquartered here, and Merit Entertainment, a touch-screen game manufacturer in Bristol, Pa., have announced plans to integrate their production and workforces.

Rowe will shift manufacturing from Grand Rapids to Reynosa, Mexico, on the Texas-Mexico border. Rowe plans to complete this shift in production by the end of 2009.The shift in production will mean the closing of the Grand Rapids manufacturing facility. Technical phone support, order entry, sales, engineering, accounting and administrative personnel will relocate to a different facility in Grand Rapids later in 2009, the company says.
