Devices are known for guiding binding material into any binding cut, which are equipped with guides to enclose the binding material in the form of a closed ring, in a rectangular shape or a similar geometric design several straight or curved guide bodies. These guide bodies are also divided along the cross-section of the binder and provided with J ¹ clocking tracks for the binder. The guide bodies are connected by springs or pressure cylinders to form a closed bypass in order to avoid uncontrolled breakout when the binder is bypassed Opening takes place either compulsorily when reversing the binding agent by overcoming the springs or by applying opposite pressure to the pressure cylinders

The guide parts or flaps kept closed by springs usually do not meet the requirement secure guidance of the binding agenti The compression springs must often readjusted, as they take on two important functions be held together firmly when driving in the binding agent in order to prevent the tape or wire from breaking out Avoid, on the other hand, an unhindered escape of the binding agent when reversing must be guaranteed. In addition, the \ 7erk-

material properties of the binding agent are decisive Factor for the reliability of the transfer process. These Refills are therefore always limited to a specific band

or wire quality limited · Furthermore, make the design der.Umführung in the area of the binding head difficulties, since the binding head in the interest of a tight Binding must be in direct contact with the binding material and thereby the pulling out of the binding agent from the spring flaps is made more difficult »The insufficient tear angle of the binding agent when pulling it out of the bypass during the tensioning process is sometimes not sufficient. This leads to accidents that affect the throughput of the binding machines - On the other hand, the guide bodies controlled by a pressure cylinder have the advantage of being safe close and open. But they are very expensive and need a large space. Besides, these are Control elements for detours that consist of several partial Pieces are put together, to be used repeatedly. Their placement as well as the simultaneous parallel opening creates difficulties and requires a great deal of design effort, especially when used in large collar presses. The use of pressure cylinders for opening and closing large ones is completely excluded Bypasses with flaps, as described earlier .-were · - But these flaps in particular have the advantage of that they can be replaced with little effort when they are worn out. This is the case with continuously machined long guide

pieces not possible Another problem has been found to be that the binding agent can escape completely freely at the circumference after opening to the side.The internal stresses in the binding agent as well as the plastic deformations caused by the drive rollers do not guarantee that this will occur when reversing binder perpendicular applying to be ligated package · It · happens in particular with extremely large bypasses that be a very different range of packet sizes _r must wältigen that the binder obliquely abuts against the package, and thus not the smallest possible looping · occupies a result, that the binding later loosens and problems arise during the transport and storage of the packages · Another specialist part of known devices results from the fact that they are only suitable for the use of one type of binding agent, i.e. either tape or wire · But this is everyone's wish Rolling mill operators, if possible to process both types of binders optionally in one binding machine.

Purpose of the invention is, therefore, an increase in the throughput while avoiding ^{Umführfehlern:} to achieve the binding machines and the quality of the bonds, as well as to allow the optional use of tie ribbon or wire as a binder in a binding machine ·

The invention is based on the object of creating an operationally reliable device for guiding binding agents, which ensures a defined opening and closing of the bypass elements through a simplified control system and which is designed to guide both binding tape and binding wire

According to the invention the object is achieved in that on a substantially the contour of the bypass forming Puhrungskörper corresponding Umführrahsen a * Puhrungskörper fixed and the other Puhrungskörper around an angle from the fixed guide body can be swiveled away # To open and close the bypass is between the Unguide frame and the movable one Puhrungskörper arranged at least one hose-like, elastic and controllable pressure member · The Both Puhrungskörper are in or outside the attack plane the pressure member articulated together by a centering element.

Purely the use of binding tape as a binding agent are on the outer sides of the Puhrungskörper angular Pührungsklappen hinged to which the pressure members issue· ?

The pressure members are subjected to pressure during the transfer process, so that the flaps and the two The guiding bodies are firmly clamped together the pressure links are relieved of the driving process,

whereby in the subsequent reversing process the binding agent Slightly push the flaps and the guide bodies apart and check the circumference of the bypass can emerge.

To choose between -binding tape or binding wire with the device apart from the angled guide flaps guideways for binding tape and a guide channel for binding wire are still provided on the guide bodies »

To facilitate the exit of the binding wire, the guide channel is arranged in the fixed guide body is provided with an outlet slope.

The surface of the movable guide body resting on the Uraführrahraen is preferably provided with a bevel, whereby the guide body can perform a pivoting movement.

The controlled exit of the binding agent from the bypass is supported by the fact that the centering element is designed as a spring pin and is arranged in the area between the pivot point of the movable guide body and the plane of action of the pressure member. ^

The advantage of this device according to the invention is that the hose-like pressure member can easily be adapted to any desired form of implementation because of its elasticity. Furthermore, the contact force on the S ¹ o'clock

elements above all: for very long detours everywhere be kept the same size

Likewise advantageous is the low space requirement, ^whereby: - _r is, for example, on large presses collar is not problematic, four bypasses accommodate the press mandrel. Even with pliers-shaped bypasses with a large swivel angle, the hose-like pressure element allows easy feeding of the pressure medium. By changing the pressure in the system, a gradation of the contact force is possible, with which different material properties of the binding agent can be compensated.

By incorporating controls into the system of the Pressure members can partially open the Umführungselernente can be achieved. Thus there is the possibility of a defined release of the binding agent on the circumference the bypass

The same effect can be achieved in that the centering element is designed as a compression spring and the contact.

grip level of the pressure member in the area between the Pivot point of the guide body and the centering element is effective. As a result, when the pressure member is relieved of pressure, a. Force effect by means of the peder one and the The bypass opens automatically. This is special favorable for bypasses in the area of a binding head, where Due to the unfavorable tear angle, the tension force is often insufficient to remove the binding agent from the bypass pull out.
