Abstract
An adhesive applicator receives liquid adhesive from an adhesive supply and has a pneumatically operated valve for controlling the flow of adhesive through the applicator to a sheet driven along a path past the applicator. A pneumatic proximity switch is located along the path for sensing the sheet as it approaches the applicator. Air from a pressure amplifier is provided to the pneumatically operated control valve of the applicator in response to the proximity switch sensing the presence of a sheet along the path. The proximity switch also can be connected to a pneumatically operated electrical switch that provides a signal to a logic and control unit for indicating to a machine operator that a paper jam exists in the event the sheet does not clear the proximity switch within a predetermined time interval.
