The single piece includes two pairs of jaws, which are continuously and continuously applied to the packaging material tube, and the tube is clamped and heat-sealed on the equally spaced cross section, and is formed into a continuous strip of pillow-shaped packaging. The individual transverse seals (i.e., the extensions are oriented perpendicular to the direction in which the tubes are fed) are interconnected. The pillow packs are separated by cutting individual transverse seals and then fed to a folding station where they are machined into a completed parallelepiped shape. The tube portion held between each pair of jaws is heat sealed by a heating device; the heating device is carried on one of the jaws and used for local melting and clamping between the jaws Two-layer heat-sealing plastic material ^

The bottom end is transversely sealed. The two clamps are opened when they reach the bottom dead center position to avoid disturbing the top of the tube; and at the same time, the other two clamps are activated in exactly the same way, from one top. The dead point moves downward to repeat the above-mentioned work of clamping/forming, sealing, and cutting. The problems associated with the forming unit are necessarily related to the so-called "modification correction" system. That is, in normal case, the packaging material of the long sheet is finally the outer surface portion of the continuation package of the I295984 (3) invention, including a series of equally spaced printed images or decorations, so the long sheet material must The forming unit is fed in such a manner that the continuous enamel ornament is aligned in accordance with the forming, sealing, cutting, and the like of the package. On the matter of K, the decoration is printed at equal intervals, and the position of each ornament relative to the shape of the upper jaw is changed. One is caused by the mechanical pressure exerted on the packaging material by the clamp. The different deformations of the packaging material, one is due to the pulsating pressure of the pourable food in the tube of the packaging material, therefore the 'requirement of the decorative position correction system' because, for the operation of the packaging machine at the skillful output speed Even if the ornament is slightly deviated from the theoretical alignment, if it is not corrected immediately, it will eventually rise to an unacceptable package that must be discarded. In the case of modern packaging machines, such a system includes an optical sensor for detecting a mark (such as a bar code), a pouring hole, which is repeated at regular intervals on the long sheet of packaging material. Or a folding line, and finally the filling tube; and a control unit for comparing the position of the detected mark position with respect to the theory. In some commercial machines, each jaw has two traction members for applying a downward pulling force on opposite sides of the tube of packaging material, and the two traction members are movably mounted to each pair. A slap in the shackle is placed on the top corner 隅 and the bottom corner of the pillow package to form a rectangular sheet. At the time of Chad's bit error I, the control unit adjusts the horse speed of the long-sheet packaging material. If this correction is not sufficient, the traction member can be controlled to slightly increase or decrease the tension of the packaging material -9-(4) 1295984. In another solution, the indexing member does not have to adjust the length of the control; and the operation is repeated again and again. For example, as illustrated by the Applicant, the two traction members are fitted to the two jaws in the respective cams and associated cam follower clocks. And in the specific case illustrated by _, in a manner that can be moved in the axial direction, parallel to the joint arm to be made at the end of the packaging material # is connected to the associated cam from the gravity of the articulated arm to the two Holding? The member moves toward the two traction members so that the packaging material can be more or less grasped at the position of the jaw. Each of the cams is laterally fixed to an associated jaw and can be stretched in a direction perpendicular to the package, primarily in the straightening direction. The movement of the cams towards the associated jaws produces a larger or smaller dynamic and smaller rotation of the lever, and thus corresponds to a smaller pulling force. The read control unit directly acts on the speed of the motor feeding the piece of packaging material until the garnish and the theoretical position of the double 颚 clip in the Italian Patent No. 1296062 is moved by a phase interaction, the former In an adjustable structure, the latter is connected to the two traction members in a rocking manner. The mechanism includes an actuating lever that is attached to the transverse sealing strip on the jaw tube in which the two traction members are mounted, and on the other end. In actual use, the shafts of the rods rotate toward each other or downward, and thus the horizontal surface of the vertical tube feeding path of the forming unit support structure of the pair of decorative objects is adjusted and has a beginning of a slope shape. The greater or lesser the degree of movement, the greater the extent to which the two traction members act on the packaging material tube or

The system control unit is activated. A fairly accurate decoration is corrected for two pairs of positions, the linear urging member being clamped to the minimum and maximum proximity. Regarding the minimum proximity of the clip, there will still be some interaction and momentum. Cause thousands of questions; In particular, when the two pairs of jaws in the forming unit are emptied and are a more significant amount of interaction than the minimum proximity of the tube with the pourable jaws, it is not difficult (I and The sterilized state is weakened. The action of each cam is controlled by the transmission moving member (ie, a pneumatic cylinder), and the decoration is corrected to obtain a tube with the packaging material during the forming process. The maximum stroke of the interactive clip, and therefore the motion between the cams and positions, must be limited, even between the cams and the opposing cams and the associated cam followers. The minimum of the traction member, which may be moved when the packaging machine is started, the sterilized packaging material tube is fed between, normal when it is flat, and the food is wider. Therefore 'even in the relative wheel, in two There is still a packaging material for the flat tube containing the food between the traction members, which is the damage caused by the traction member. Therefore, the invention aims to provide a forming unit in the first embodiment. For packaging made of packaging material tube filled with tiltable ^ ^ ^ ^ ^ 〒 ^ sealed packaging, and designed to avoid the typical association of the known unit missing.

When there is any difference between the actual and reference position of the ornament, the central control unit 75 will command the % of the actuators 6, 6 to adjust the position of the associated cam 30 on X and adjust accordingly. The pulling force exerted on the tube 3 by the associated traction member. More specifically, the activation of the actuator 36 causes the round rod 43 to rotate about its axis such that an eccentric connection between the round rod 43 and the block 34, the cam 3〇, is provided at -21 ^ 1295984 (16) |^ Explain that the $^ direction of the water + surface moves, containing the required components. The above operation, i®, is repeated until the actual position of the ornament matches the position of the reference. When the field starts the unit 1 '? The movable member 58 of the damper 56 is set in the retracted position (Figs. 4 and 7)' corresponding to the retracted configuration of the toggle mechanism 55 and the incompetent configuration of the associated cam follower 32. When the assemblies 6, 6 are moved downward, any interaction between the cam follower 32 and the associated cam 30' itb & f is such that the two traction members 25 remain in space. Any interference between the two traction members 25 and the empty tubes 3 of the packaging material fed along the path p can therefore be avoided, thus eliminating the tube, any damage or reducing the risk of disinfection. Obviously, there may be many changes to the unit described herein without departing from the scope of the patent application. In particular, unit 1 may comprise two series of jaws 8a and 8b as part of a chain conveyor defining respective endless jaw paths, extending on opposite sides of the tube 3 feed path and cooperating with each other. . If this is the case, each of the forming assemblies 6, 6' will be defined by a clamp of one of the two transporters and a corresponding clamp of the other transporter.
