W. Amsler Equipment, Inc. extends its line of leak testers with an innovative flying head design, which provides high output, flexibility and tool-free changeovers. The five-head unit, which runs up to 250 bottles/min, is for plastic containers up to two liters. The heads travel with bottles along the conveyor in the enclosed system and feature the use of servo motors instead of an indexing conveyor or stationary heads to control the traveling heads. No change parts are required and tool-free changeovers are fast and simple. www.amslerequipment.net
