Abstract
ABSTRACT OF THE DISCLOSURE
The primary thrust drive for a punch and die set which presses together two superimposed portions of the band to be locked utilizes the mechanical advantage afforded by a symmetrical angle lever pair. The arms of the levers are turned about a pair of pinions by a pneumatic piston drive. At the end of the other arms is a pressure roller which rides on a pressure surface of a pressure plate to convert the rotation movement of the angle levers to an outward linear movement on the pressure plate towards the pinions. The pressure plate carries the die. The pressure surface upon which each of the rollers acts is made to have a cylindrical curvature away from the roller. This has the effect of making more linear the characteristic increase of the mechanical advantage of the toggle arrangement as a function of the outward travel of the pressure plate and thereby making the adjustment of the die travel less critical.

Description
The invention relates to an apparatus for locking band hoops on packages by permanent deformation oE two superimposed portions of a flexible hooping band. rrhe deformation of the portions is brought about by press:ing down a die arrangcd in raisable and lowerable manner over the portions. The bottom of the die is fixed to a pressure plate which is guided in the casing of the apparatus and toward a punch mounted in a base plate of the apparatus and positioned below ~-the portions. ;
There are fundamentally two groups of known apparatusfor locking band hoops. In the first group, locking is accomplished by means ~ a lockiny sleeve w}licll is placed over the superimposed portions of the hooping band and is deformed together with the band portions to form a non-detachable connection. In the second group, which apparatus is used mainly for locking flexible metallic bands or strips, locking takes place without a sleeve, i.e. through reciprocal permanent deformation of the superimposed portions of the hooping band.
In the case of the second group of apparatus, the forces to be applied for deforming the superimposcd portions of the hooping band are very large because a non-detachable connection has to be produced without using a locking sleeve.
To this end, the band portions are placed between a punch mounted in the base plate of the apparatus and a raisablc and lowerable die spaced above the punch. The die is pressed ~ ::
- ~ ~ 0~3;~33 down with great force onto the band portions either manually or by means of a power drive until the permanent deformation of the band portions necessary for the non-detachable connection is achieved.
In order to obtain a permanent non-cletachable connection between the band portions, it is important that the movable die is precisely aligned with the punch mounted in the base plate in order to bring about a perfect cooperation between the protuberances and depressions arranged in both these tools. ~lowever, this is not sufficient for obtaining a suitable connection if the force applied is insufficient.
In known apparatus of this type, the necessary force is provided through force transmission lirlkages, such as toggle linkages. When such transmission linkages are used within a small lifting or stroke range, rapidly increasing forces are exerted. If the stroke travel is set too far, the resulting excessive force can lead to the destruction of the apparatus during the locking process. If the stroke travel setting is made too short, the necessary minimum deEormation for the locking process is not obtained.
The present invention provides an apparatus of the type indicated hereinbefore that tlle value of the pressure force is varying in an uniform manner as a function of the stroke, and the lateral forces acting on the die are absorbed in the immediate vicinity thereo and conducted into the base plate.
0~3 333 According to the present invention there is provided an apparatus for locking band hoops on packages by permanent ' deformation of two superimposed portions of a flexible hooping band, said apparatus being of the type b~ which the deformation of the band portions is brought about by pressing down a die arran~ed in raisable and lowerable manner over the portions, A wherein the improvement comprises, a punch mounted in a base ¦ plate of said apparatus and positioned below said portions, a die facing said punch, and a pressure plate to which the bottom of said die is fixed, said pressure plate being guided in a ~ casing of said apparatus toward said punch, the top of said ; pressure plate being constructed as a pressure surface for the end of a first arm of two angle levers mounted with a horizontal spindle in said casing, the force Eor operating said toggle levers being applied to a second arm of said levers rigidly connected to said first levers at said spindle.
According to the invention, therefore the top of the pressure plate is constructed as a pressure surface for the end of a first arm of two toggle levers mounted with a horizontal spindle in the casing, whereby the force for operating the toggle levers is applied.
The present invention will be further illustrated by `-way of the accompanying drawings in which:
Fig. 1 is a side view of an apparatus for tensioning and locking band hoops, with juxtaposed locking and tensioning parts;
Fig. 2 is a vertical section through the locking part 3 of the apparatus of Fig. 1.
The apparatus shown in Fig. l for tensioning and lock~
ing band hoops or straps has a base plate above ~hich is positioned a band channel, accessible from one side, for insert-ing not shown superimposed band portions of a flexible hooping hand. In base plate l there is mounted a punch 3 which faces a 3.~3~
movable die 4 fixed to a primary thrust drive mechanism. Punch 3 and die 4 are deformed at their pressure suxiaces in such a ~ that on pressing do~ of the die 4, the superimposed band ¦ portions are permanently deformed to give a permanent connection.
S A casing 5 in which is fitted a primary thrust drive mechanism for the die 4, as will be described hereinafter ¦ relative to Fig. 2, and which is connected to base plate 1, is positioned above band channel 2. A further secondary thrust drive mechanism with a thrust rod 6 is fittet in the casing 5 alongside the primary thrust drive mechanism. Thrust rod 6 is ; articulated via a swivel joint 7 to a tensioning housing 8 which is in turn mounted via a swivel joint 9 on casing 5. Thus, ~ tensioning housing 8 can be pivoted about toggle joint 9 by ;i means of the associated secondary thrust drive mechanism via thrust rod 6.
In the tensioning housing 8 there is pivotably mounted a tensioning roller 10 which is operable either manually or, as shown in Fig. 1, by a motor drive 11, e.g. an electric or pneumatic motor. For placing the hooping band in band channel

1 bracket 30 is connected to a piston 31 which is guided in movable ~ manner in the upper part 32 of casing 5. At the transition from upper part 32 into cover part 33 a feed line 34 is provided by i means of which a fluid pressure medium can be supplied to the j primary thrust piston drive formed by components 30 to 33.
