Patent number: 4360938Abstract: In tack seat lasting machines, variation of the tack (nail) pattern is achieved by varying the wiper inwiping movement, itself dependent upon their lengthwise movement. Such variation also alters the "back tack" position (i.e. relationship between the heel band backseam region and corresponding region of the wipers). In accordance with the invention, the nail pattern is varied by an operator-set reference potentiometer (198) by matching with its signal that of a linear potentiometer (190) which controls operation of wiper-operating motor (72, 74). The back tack position is controlled by a motor (105) according to an operator setting of a reference potentiometer (208). The combined signal from the reference potentiometers (198, 208) is compared with a control signal of a linear potentiometer (202) associated with the heel band, the motor (105) being operated until the compared signals match.Type: GrantFiled: January 22, 1982Date of Patent: November 30, 1982Assignee: USM CorporationInventors: Brian J. M. Murphy, Leslie A. Withers, Malcolm Salway-Waller
