Position the magazines manually in front of the pushers ensuring that the lateral guides are adjusted correctly. The pushers feed the magazines into the film former (forming box) while they are sealed longitudinally by a sealing unit. The envelopes will move along an idle belt dragged by 2 pliers which will alternatively provide for welding and cutting the envelopes as well as unload them through the opening at the exit of the maschine. The magazines can either be loaded manually or by using a synchronised loading unit (optional). The feeder is connected to the machine as follows: connect the A (interfacing) cable with plug 1 (on the feeder) and with plug 2 (on the machine) connect the B (voltage) cable with plug 3 (on the feeder) and with plug 11 (on the machine). Plug 5 (on the feeder) will be of use if more than one feeder is required to supply the machine. It is intended to connect in series 2 feeders to each other or more than two feeders. N.B.: if there is an extension installed upstream of the machine, the machine pushers must be synchronised with those mounted on the extension. Act as follows to regulate the exact position from which the pushers shall start: hold down button 9 MANUAL, press key 12 START to give short pulses in order to bring any S pusher in a fall position (figure 1) adjust the dowel (V5) to position the micro tracer point (figure 2) Envelope and rear length adjustment L Envelope length X space directly related to L Y rear. The arrow will show the direction in which the product is moving. Envelope length The envelope length can only be set up while the machine is moving. Before providing for the adjustment, it is recommended to press buttons 8-9 at the same time to disable the micro switch (slow film) (a lighted led on the 1 - FN display will show that the micro switch has been disabled). Turn potentiometer 22 to adjust the length of the L envelope from 120 to 420 mm. Turn it counterclockwise to lengthen the envelope. Turn it clockwise to shorten it. The actual measurement expressed in millimetres will automatically appear in the LGTH display (3). After establishing the desired measurement and re-enabling the dandy roll micro switch (slow film), the machine is ready to start packaging. Rear In order to regulate the length Y, use keys 10 and 11 to modify the value that appears in the REAR display. This can be set to any value between 1 and 9 (each number is equivalent to approximately 2,2 mm). Increase the value to increase the Y length and vice versa. Set the rear value so that the envelope is sealed/cut at the mid-point between the two magazines. 18

Films to be used The machine can work with all heat-shrink and non-heat-shrink films (polyethlylene and polypropylene), from 15 to 30 microns in thickness, of a technical and food type. To guarantee the best results, use the films marketed by us. The special features of our films (which may be customised with drawings and text) assure their outstanding reliability, with regard both to compliance with laws in force and to excellent machine performance. Consult the data and safety sheets of the films in use and observe the corresponding instructions! Maximum reel width: 650mm Chapter 5. Safety standard 5.1. General precautions THE MACHINE CAN NOT BE USED BY UNTRAINED PERSONNEL! Before acting on the machine to adjust, service and repair it: put the machine in safe conditions by pressing the emergency button arranged on the control panel power off the machine by turning the main switch to 0 remove the supply plug. The removal of cases, doors or walls in unsafe conditions may cause the operator/maintenance man to come into contact with moving members, hot parts and live devices If safety devices are either removed or tampered with by the user, this will relieve the supplier of any civil and criminal liability Specific precautions The welding pliers which will alternatively move will never reach a high temperature which may be considered as dangerous. However, never touch the welding rod (or the hot wire) arranged beneath the lower profile of the welding burner and hidden between the 2 film pressing slides. Pay great attention when you are working in the proximity of the members above since there is the potential risk of accidentally coming into contact with very hot parts. The device for the central welding will keep a higt temperature many minutes after the machine has been disabled and its protections have been opened. Pay great attention when you are working in the proximity of the members above since there is the potential risk of accidentally coming into contact with very hot parts (200!). It is recommended to use protection gloves. The reset of the machine in automatic mode will necessarily require the inspection doors to be closed. The machine is complete with a safety micro switch which will signal when the trasversal welding area cover 7 is open (figure 1.3. page 15). This device will cause the machine to stop when the cover above is open. In case of blocking of the machine or in order to stop it during the automatic cycle press the EMERGCY PUSHBUTTON (7). Rotate clockwise to release and press the RESET button. 20
