The nose plate 18 serves in its actuated position as Base against which the friction welding device works when sealing the loop ends of a packaging tape. To achieve a high degree of intransigence of the nose plate in this position, it is desirable that the lias plate in the in the The groove 22 provided in the base plate has a tight tolerance, without prejudice to that caused by the pivoting mounting of the levers 21 Tending of the lias plate to perform an arcuate movement.

The rabbits plate 18 is therefore applied to the levers 21 pivotally gelagert.und for example, with the force of a torsion spring, which presses the plate in the viewing direction of Figure 3 in the counterclockwise direction resiliently in a particular by the abutment against the lever 21 limiting position. In the retracted state, the nose plate 18 assumes this limiting position with respect to the lever 21, which is such that the lower edge of the nose plate is not pivoted below the horizontal plane of the underside of the base plate 13 when it is moved into the operating position is shown, the lower side of the opening of the groove 22 is recessed, which facilitates the insertion of the nose plate 18. The dimensions and the mutual arrangement of the parts are chosen so that the nose plate is inserted into the groove with a substantially rectilinear sliding movement, there is little or no inclination movement with respect to the groove.

As shown particularly in FIGS. 4 and 5, a metal block 30 of some length is arranged between the gripping members 15 and 19 in such a way that its two ends each remain at a distance from the relevant, adjacently arranged gripping member . The block 30 is formed on its lower surface at 31 between that block end which is adjacent to the gripping member 15 and a vertical stop surface with a recess provided at a central point in the longitudinal extension of the block.

The slot 33 is inclined towards the turf plate 18 in such a direction that it is substantially in alignment with the opening 15a provided in the gripping member 15 with the gripping member 19 ^; lies. The block 30 extends beyond the plane of the gripping members 15 and 19 away from the frame structure and is ang-articulated at this point at the free end of an arm 34 of an angle lever 35, which in turn is pivotable in its center with a fixed pivot point 36 on the frame structure 14 is stored. The other arm 37 of the lever arm 35 extends between the gripping members through to the rear and is loaded at its outer end with the upward force of a tension spring. The spring force of a second tension spring 39 is applied between a pin 40 provided on the angle lever 35 and the block and presses it down into a position of firm contact against the ITase plate 18. At an alitated point in the longitudinal extension of the arm 37, a pin 4I is provided, which is received in an opening 15b formed in the gripping member 15, which is arranged above the opening 15a.

A cutting device with mutually movable, in cutting jaws 42, 43 arranged at a distance from one another is between the gripping member I5 and the adjacent end face of the block 30 arranged.

1 Certainly can be a polypropylene tape, from a tape supply through the opening 15a of the gripping member 15 for the free end of the tape as well as between the cutting jaws 42, 45 of the movable cutting device inserted through into the guide groove 33 of the block 30. Since the open side of the guide groove 33 closely adjoins the frame structure I4 there is no fear that the strap could slip sideways out of the hat. This passes through the guide groove 35 Then tape between the gripping link IQ and the rabbit plate 18. The free end of the tape applied in this way is then used for the binding process is guided around the pack by hand or automatically along a continuous guide rail. Then will the free end of the tape zf / ischen the gripping member 15 for the free end and the rabbit plate 18 and passed under the cutting jaw 43 of the movable cutting device and between the lower Recess surface 31 of the block 30 and the rabbit plate 18 inserted. This insertion is continued until the free end of the tape comes into contact with the end plate 32, which serves as an end stop, when the tape involves the actuation of a sensing arrangement or response device arranged at a suitable point on the loop web triggered by a drive motor for the tape feed and -Tensioning device is switched off and the compressed air cylinder G1 is put into operation, which in turn now causes the gripping member 15 moved down and the tape against the nose plate 18 tightened. During the downward movement of the gripping member 15, the pin 4I carried by the arm 37 of the angled lever 35 is also pushed through engaging the upper palm of opening 15b on the pin 41 carried so that the lever 35 in the viewing direction of Figure 5 is pivoted clockwise about the pivot 36, as indicated by the arrow. Since the guide block 30 is articulated to the arm 34 of the angle lever 35, the Guide block 30 in the course of the pivoting movement of the angle lever 55 retracted or disengaged with respect to the nose plate 18 to a position remote from the position of the tape, albeit it also remains in contact with the rabbit plate 18 in this position. The overlapping tape ends are therefore no longer subject to the guiding action of the groove 33 and the recess 31, but rather are freely arranged between the vibrator block 26 and the lens plate 18.

The packaging tape is then tightened using the first tensioning device 11 and the second clamping device 12 in the manner in Tightened and tightened towards the tape supply as suggested in pending UK patent application 37690/67.

As soon as the required strap tension has been achieved in the loop, one is actuated with the strap tensioning device connected pressure reducing valve for supplying compressed air to the cylinder G2, which then causes the gripping member I9 to close, so that the tension in the belt loop is maintained by the gripping of the gripping members I5 and I9. Simultaneously with it there is a decrease in pressure when the pressure reducing valve is actuated the tension in the length of the tape between the gripping member I9 and the | l tape supply effected.

The pressure reducing valve also releases actuation of the vibrator block 26 to weld the overlapping ends of the Tape into a permanent welded joint. The welding process is brought about that the block on the loop ends is actuated to a very fast reciprocating rubbing movement, so the tape material on the contact surfaces for Bring melting. The pressure applied during this procedure and the duration of the process is such that the loop ends are welded together, whereupon this process ends will.

While the vibrator block 26 is in contact with the belt

f , the movable cutting jaws 42, 43 are actuated at the same time to separate the sealed tape loop from the tape supply.

The gripping members I5 and I9 are then guided upwards and the air cylinder MP is used to take out the nose plate 18 actuated from the groove 22 and to transfer the plate into the retracted position. When the nose plate 18 is disengaged their position in the groove 22 are the nose plate 18 and the guide block 30 as a result of the tensile stress prevailing in the sealed tape loop against the force of the torsion spring 28 downwards pivoted so that the sealed loop of tape slides down from the nose plate 18 and so pushes it out of the hash ine p will.
