The gripper is associated with an electric heater which is in contact with the gripped straw. In the bonding section, an electric power supply rail is provided so that a collector of the heater slides on the rail, energizing the electric heater to heat the heat-bondable portion of the wrapped straw. In the bonding section, the heater is also pressed against the carton travelling in a production line at the same speed as the moving speed of the heater with the heat-bondable portion of the wrapped film therebetween. Thus one film wrapper is heat-bonded to each carton. After the completion of bonding, the cam operated gripper releases the straw allowing the straw to remain attached on the carton. | |
