Description

In connection with slide-in folding device, one folding panel and one together with it it finally became known., the in working slidably trained folding slide

solved in that the effective folding edges of the Folding plate are mutually offset.

In order to be able to change the intermediate folding lengths of several folded goods within certain limits, are according to a further proposal of the invention, the effective folding edges of the folding panel in their mutual offset formed adjustable.

Around the folded goods that are folded to different intermediate folding lengths in the first folding station Before carrying out the last folding process, stack them on top of one another with edges parallel to each other and then use them during the formation of the

S reached form to lead to a stacking point. ^

Ig; A multiple folding device was proposed for the staggered interfolding of several foldings - the last two folds. The first folding station beats several with a single fold, the first folding station with a foldable folding slider and slide-in folding plate working together with this cooperating side folding surfaces, which are preceded by _-u: .u ", ·."»,;._{a.; "o",}";♦" ci-- _.::. .: · _ _{Thrust of} p _a i _tgutes are formed intermittently nearly inserted into the folding plane of the folding plate.

When removing the folded items, it is necessary to put the package thus formed in the to secure the mutual position of the folded goods achieved by the last folding and in particular to avoid damage to the package. This is achieved in a particularly simple manner that im Fold path of the folding slide of the second folding station a cycle in a manner known per se on a discharge

be brought to the first folding station. From an initial lateral length to a uniform intermediate size folded items are laterally shifted to one another and stacked on top of one another on the deflection surfaces, to then with the help of FaItst. Through the folding channel of the second folding station to be felt through. Because the folded goods are laterally shifted to one another on the deflection surfaces are on top, there is a graduation corresponding to the extent of their offset on the parcel folded in this way,

has slide and a second folding station with a folding slide which can be pushed into a folding channel wherein the second folding station has a plurality of deflecting surfaces arranged at a distance one above the other for the material to be folded, which are designed to be slidable one after the other into the plane of the first folding station are and the deflecting surfaces each assigned cyclically controlled side shifting devices are. The folded items to be combined into a group are successively removed from the both side folding slides folded around the folding plate conveying direction facing the folding shaft wall than between the dispensing conveyor belts swivel-in strip plate is formed.

An embodiment of the invention is explained in more detail below with reference to drawings. It shows

According to Fig. 1, the folding device has three Conveyor belts 1 running parallel to one another and guided around deflection rollers 2 Die Umlenkrol

Layers of the folded items which are folded into one another and which are guided around deflection rollers 2. The pulley are on top of each other. This leads to the disadvantage that len 2 are mounted on a shaft 3 in the frame that at one end of the package formed in this way the device is mounted and not dartic from one end only four layers, but at the other end the brake motor is driven. The mining twelve Layers on top of each other. If you set the bands 1 are also not shown at the beginning of the two folding processes described 50 pulleys performed, which are also in Geim generally still carried out, the width of the alternately mounted axle 4 are arranged. Above Faltgutstückes bisecting longitudinal folding ahead, so the conveyor belts 1 is one of their support surfaces there are eight folding panels 5 at one end of the package and at the one at the essentially parallel folding panel the end of which, however, 24 superimposed layers of the provided by a also befe-Faltgutstückes on the frame. So that this folding device only 55 continuous carrier 6 is added. As shown in FIG. 1 for comparatively thin pieces of material to be folded are suitable, for which it is obvious, the folding plate 5 is on one of its two

On the other hand, it is thicker folded items due to the 24 or eight superimposed ones Layers resulting in unequal stack heights are not very suitable.

The invention is based on the object of creating a folding device that enables several Folded items to be combined to form a package ta a single folding process on longitudinal sides of one another stepped off and thus has three folded edges 7, 8, 9. Work with the folding plate 5 two side folding slides 10, 11 arranged on the side of the conveyor belts 1, one transverse to the conveying direction and also upward and then carry out the work movement directed backwards.

Be there second folding station 12 arranged, which one in a two side parts of each Faltgutstückes on the Folding slide 13 that can be moved in the vertical plane on both of their initial position moved apart has, which is received by a carrier 14, engaging side folding slide 10, 11-at its end facing away from the folding slide 13 is 5 ben, while the middle part of each folded item of the carrier 14 with a T-shaped guide piece between the conveyor belts 1 and the FaIt-15 is provided, which is located in a stationary guide plate 5. The two side folding slides 10, 11 track 16 slides On the guide track 16 is a guide first upwards and then on one-Zahnungl7 formed, with which a pinion 18 in the other to directed work out and fold This pinion 18 is inwardly reversed by a switchable push-in motor 19 attached to the carrier 10, the two side parts of each folded item 14.
