A strapping tool has a timing control circuit incorporated therein which comprises a first pressure-operable valve for time-controlling a plastic strap welding operation, and a second pressure-operable valve for restricting fluid line flow from a source of fluid to an air drive motor of the tool during the tensioning phase of the strapping operation while permitting unrestricted fluid line flow from the source of fluid to the air drive motor of the tool during the welding stage of the strapping operation.
Outil de cerclage possédant un circuit de commande par minuterie intégrée qui comprend un premier robinet manométrique afin de commander d'après le temps le soudage d'une bande de plastique, et un deuxième robinet manométrique pour limiter l'écoulement du fluide dans la canalisation à partir d'une source de fluide jusqu'au moteur à air comprimé de l'outil pendant la phase de mise en tension au cours de l'opération de cerclage tout en permettant un écoulement sans restriction du fluide dans la canalisation à partir de la source de fluide vers le moteur à air comprimé de l'outil pendant l'étape de soudage de l'opération de cerclage.
