DE2809920A1 - Book edge polishing machine - comprises motor driven endless abrasive belt below page guide bars - Google Patents

Abstract

The polishing machine consists of a box structure on which a motor driven polishing tool e.g. an abrasive belt is mounted. Channels are mounted at either side of the polishing tool, through which the dust is sucked away and deposited inside the box. To polish an edge of a book, the covers are hinged away and the pages are clamped between two rails. The edge of the book is then moved by hand over the polishing tool.

Description

"Bookcut Grinding Machine"

The invention relates to a book section grinding machine u ,, grinding away dirty book cut surfaces.

Depending on general environmental pollution, loan frequency and care behavior the readers and library staff inherit books in scholars and Public Bihlicht a more the less strong degree of pollution. That The main focus is on the visible exterior of the books, such as the book cover and book cut (= cut edges of the sheets of a book grouped together to form a book block Book).

Among other things, the degree of external soiling also determines the service life of a book and thus has a considerable influence on the annual book procurement budget a library.

This, in turn, is the reason why libraries maintain bookkeeping departments, with the task of extending the life of the books through maintenance measures.

It is known that the serging of soiled search cuts in the Libraries, too, are still taken in the traditional way ro; Using an eraser or sandpaper is used to clean up a dirty section of a book by hand; this work is time-consuming and labor-intensive, an effective, uniform ster di surface itself Extensive renewal effect of the book cut is not achieved.

Up to now there is still no device with which this cleaning process could be simplified, accelerated and intensified.

The object of the invention was to provide a device for serging and To freshen up the book cut (overcut, head cut, black cut), with which @@@@@ the time-consuming and personnel-consuming and ineffective cleaning the process can be simplified, intensified and accelerated by hand.

The object is achieved according to the invention by a device for Grinding of the book cut of books, which is marked by the fact that it has an electromotive operation @@@ grinding tool (disc, belt, mop, etc.), preferably on the bookcut held and zussmmenoe oreßte by the side clamping jaws brought up by hand on its surface as far as the grinding tool ang @ sch @ iff @@ is that the impurities are removed (sbg @@ chliff @@) and the bright, Uncontaminated paper forms the nese @@@@ - area of the search cut. The Bei Sanding process @@@ standing paper sanding and dust can be done at the same time by @@@ suction device operated by an electric motor can be collected.

As a further development of the invention, the grinding tool @@ in his Shape does justice to the fact that the book cut @@@ is not flat; for example, the Front cut of: L'ch "s be designed as a hollow cut. As a result, there is. Create a grinding tool made of material and shape in such a way that it is such Can adjust training and unevenness of the surface of the ßuchschnittes.

Because the head cut and tail cut through the higher-standing you ch binding are limited at the spine of the book; are the clamping jaws of the device with a locking or marking device. The book clamped so laterally is therefore not caught on the back binding by the grinding tool and may be injured.

The device is also maximally common in its dimensions Book formats (length x width x thickness).

In addition, the grinding tool will preferably be such that that unintentional injuries to the worker are excluded.

The abrasive material used on the grinding tool uirc in its Condition of the material to be processed (Pacier).

The process of grinding can also become a VCrrang 'of polishing of the beveled book section. All that is needed for this is the grinding tool exchanged for a polishing tool or such a tool is next to the grinding tool angeord @@@@ Numerous modifications of the embodiment described are possible.

Thus, instead of from above, as described above, ad book can also be used in front of below or be brought up to the grinding tool from the side; also can instead of the book to the grinding tool, and vice versa, the grinding tool to the book be introduced. The invention can also be used as a table aggragit be designed as a handset.

The advantages achieved by the invention are in particular: that the hitherto ma @ ual work process of scuffing. mechanized and accelerated is that the book is held by a simple clamping device and on Book cut is pressed together so that a uniform cut across the entire width of the cut Surface removal of the paper takes place and that the Paper dust is sucked off and collected.

An embodiment of the device according to the invention is in attached drawing explained in more detail.

The drawing shows the box-shaped attachment or substructure 1 in which the motors, drive units, the suction blower, the receiving chamber for the paper sanding etc. are provided.

The upper box opening exposes the grinding tool 2, onto which the Book is lowered.

The book grind is taken up by suction nozzles 3 of the suction device.

Hold the preferably manually operated lateral clamping jaws 4 the book block, molded the Uuchcut together and lower the book onto the grinding tool off, for grinding the front, head and tail cuts.
