Description ; San has been using thermoplastic for a long time Saterial &: ur 'manufacture of' book covers of all Arte These book covers are characterized by good watchability and high resistance against mechanical stress and are therefore particularly suitable for lending and school offices, but up to now they had to be manufactured according to the width of the book spine.

Es wurde nun eine Buchhülle gefunden, die es erlaubtdaß sie für verschiedene Buehstärkeu verwendet werden kann. Diese Buchhülle besteht aus den beiden Seitenteilen ? und 2 und dem Rückenteil 3. Der Rückenteil wird nach der Er- £ e ve3rt spesiel erksou ; en iD3 findungjmit Hilfe on speziellen Werkzeugen im, H&chfrequenzschweiß-cder Wärmeimpulsverfahren mit harmönikaartigen Eangsrippen in beliebiger Anzahl versehen. Statt der ängsrippenkamman den Rückenteil auch mit einer kreppartigen Prägung versehen, die ebenfalls wie die Längsrippen eine starke Ausdehnung des Rückenteils zuläßt.A book cover has now been found that contains it allows them to be used for different levels can be used.

The back section is £ e ve3rt spesiel erksou; en iD3 finding with the help of special tools in, H & chfrequency welding of the heat impulse process with harmonica-like ribs in any Number provided. Instead of the longitudinal rib comb the back part also has a crepe-like embossing which, like the longitudinal ribs, allows the back part to expand considerably.

Dadurch entsteht eine quer-elastische, harmonikaartige Zone, die sich bei Büchern mit breiteren Rücken dehnt und bei Brchern mit schmaleren Rucken entsprechend zusammenzieht. Hierdurch wird gewährleistet, daß die Buchhülle das Buch immer fest umschließt und sich außerdem für Bücher unterschiedlicher Stärken verwenden läßt. Schutzanspruchy Buchhülle aus thermoplastischem Material vorzugs- weise solchem aus PVC, dadurch gekennzeichnete daß ihr Ruckenteil mit Hilfe besonders geformter Werkzeuge im HochfrequenzschweiB-oder Wärme- impulsverfahren it harmönikaartigen in Längsrich- This creates a transversely elastic, harmonica-like zone that stretches for books with wider spines and contracts accordingly for books with narrower spines. This ensures that the book cover always tightly encloses the book and can also be used for books of different thicknesses. Protection claim book cover made of thermoplastic material, preferably wise such made of PVC, characterized that her back part with the help of specially shaped Tools in high-frequency welding or heat impulse process with harmony-like in the longitudinal direction
