In a device for cutting to length and feeding spine strips () for a case maker (), a center strip conveying device () is provided that advances the spine strip material () by the spine width (B) transverse to the board feed direction () in a cyclic fashion. The spine width (B) can be changed from work cycle to work cycle without accumulating additional waste. This can be realized because the previously required width sizing on the material web is eliminated.

Device for cutting to length and feeding spine strips for a case maker

The invention pertains to a method and apparatus for producing cases with rounded corners. According to this method, the corner edge () that protrudes in the region of a rounded corner () is initially uprighted and turned over and subsequently pressed on the cover boards () together with the turning-over and pressing-on of the lateral edge () of an adjacent lateral border, in the same station (). The apparatus comprises at least one rounded corner tool () that is arranged in the same station () in the which the lateral edges () of opposed lateral borders that lie parallel to one another are uprighted, turned over, and pressed on the cover. The rounded corner tool () can be moved (b) toward the center of the case and out of the effective range of the lateral turn-in device () immediately before the turning-over and pressing-on movement (c, d) of the lateral turn-in device ().

Method and device for producing cases with rounded corners

An apparatus for manufacturing book covers having a board feed for supplying cover boards and a spine insert having a covering material feed for supplying covering material, having a covering material cylinder, by means of which the supplied covering material is taken over, conveyed past a glue spreading roller and assembled with the supplied cover boards and having a folding and pressing apparatus as well as having a delivery apparatus and having a drive apparatus for the covering material feed, the board feed the covering material cylinder and the folding and pressing apparatus it is provided that at least the covering material feed the board feed and the folding and pressing apparatus are drivable in each case independently of one another. The covering material cylinder is preferably also provided with an independent drive. The independent drives are preferably servomotors, which are designed in each case as a slave and follow a virtual master The essential advantages of said apparatus are product-protecting and efficient fault handling as well as simple setting-up and correction operations.
