Device for splitting flexible sheet-shaped sheets.

The invention relates to an apparatus for splitting flexible sheets Sheets (e.g., paper sheets, cardboard sheets, pollen, and the like sheet-shaped objects) into compact packages, with the arches having different sizes and / or proportions can and should be folded into packages of predetermined size and proportions. This device is special, however not only suitable for splitting blueprints of different lengths and / or widths and the like.

The main purpose of the invention is to make known arched trap door;!. Te in relation to oinon or moreoro of the followers Points to improve: simplicity of construction and / or puncture, speed of work, reliability, versatility regarding the splitting of arcs with different Format, noticeable reduction in set-up time when changing the format, simple control, easy adjustability and maintenance and small size and compactness of the device, making it in a protective and dust-proof Housing can be housed, forms a unitary machine and takes up little space. the

The invention provides an essential "in relation to all of these points." Improvement over known folding devices.

Some of these benefits come in part with devices too achieved as described in U.S. Patents 3,052,464 and 3,117,777, but the invention provides a significant improvement on the other hand, in particular in terms of speed, reliability, versatility and ease of operation and function.

To achieve this, the invention comprises a selective one Control device which is designed so that an operator . only needs to be minimally trained! in order to to operate the device in such a way that this arcs with various Fold the format into a package with a predetermined length and width and thereby the text fields (in the case of ■ drawings) uniformly arranged in one corner of the package surface.

According to the invention, the device preferably includes a mechanism / which is adapted to initially have a or several transverse folds in a sheet (i.e. transversely in the longitudinal direction) and / or cross folds at variable distances from one iiand the sheet produces, and furthermore (if this the sheet dimensions require) a mechanism which is designed so that he the once folded sheet another world-; Times or several times across the previous one Folding direction, i.e. crosswise, automatic and / or

The main components include the infeed and folding rollers 22, 24, the lower pocket 20, a solenoid operated lock 50, which is arranged between the upper rollers 22, 24, the conveyor 25 and the rear package receptacle 26. The lock 50 includes sheet guide fingers 50a which can be positioned in grooves 22a in the upper input and folding roller 22 and lowered into this position by a lock lifting magnet G-3 (FIGS. 7 and 8) or by springs 50b in the ones shown in the figures 5a, 5b shown position. can be lifted. . .

The lower pocket 20 consists of two only slightly spaced apart Plates 52, 52 (FIG. 8), which take a sheet take ta form. The effective depth of this pocket is determined by adjustable stops, which can be adjusted so that they are passed through slots 20a (Fig. 7 and 10 ·) protrude into the pocket, which will now be described.

An upper, horizontally running, pivotably mounted stop rod 53 is provided with several stops 44 protruding apart from one another. A second horizontally pivotably mounted stop rod 55, which is arranged below the stop rod 53, is provided with similar protruding stops 56, and a third, normally fixed stop rod 57 is provided with protruding stops 58 . The lower

To explain and deepen what has been said, but not for the sake of limitation, further features are given below and advantages of the invention described in more detail.

The coordinated drive of the input rollers and cold rollers of the conveyor u 25 and the conveyor 33 and the fast and precise selection and operation of the various dispensing mechanisms, Stops and associated ropes enable a high operating speed in the Jra'J ton one Pause with a standardized size or when splitting a ge cical standardized sizes or excessive, non-standardized sizes, which can also be mixed according to standardized sizes.

The trails are preferably arranged in such a way that they illuminate the pressure knots from the inside, whereby these see through inend, so that.3 the inscriptions are clearly visible on it.
