Abstract
A twin-tube tubular bag machine having two longitudinal sealing elements for forming two parallel film tubes, two parallel transverse sealing jaws for forming sealed tubular bags, and two filling devices for filling the tubular bags. A dosing device is disposed upstream of each of the filling devices for dosing a prespecified filling quantity of the filling material to be filled into the tubular bags. A transfer element having several transfer containers is provided between the filling devices and the dosing device. The filling material is transferred from the dosing device to the transfer containers in an input station. The transfer containers are transported to a pairing of two dispensing stations along a transfer line, the filling material is transferred from the transport containers to the two filling devices, and the transfer containers are transported back to the input station along a return transfer line.
