An apparatus for feeding spine inserts for a machine for manufacturing book covers having a take-off roller system for withdrawing in clocked synchronism a material web cut to width by further means from a screening roll, having a cutting device for cutting off a portion of the material web as a flexible spine insert, having means of introducing the flexible spine insert into a board feed plane and having a board feed, which pushes the spine insert and further cover boards, for synchronous feeding of the boards onto a covering material, which has been coated with glue at a glue spreading roller and fed by means of a covering material cylinder a take-off roller system is provided, which inserts the material web counter to the board feed direction into the board feed plane and with which are associated guides for guiding the advanced spine insert and means of further guiding the cut-to-length spine insert as far as into the board feed plane. The take-off roller system is situated preferably upstream of an intermediate position of cover boards advanced in two successive strokes, so that in the region of the intermediate position a board screening feed hopper with rigid spine inserts may be disposed. The spine insert is fed jointly with the cover boards by the second stroke of the board feed to the joining point.

Apparatus for feeding spine inserts for the mechanical manufacture of book covers

A device for storing and unrolling materials in web form in bookbinding machines having a roll-changing device for connecting a material which is to be unwound from a roll to the end of a material of the same kind unwound from another roll. The two rolls of material are placed, resting on their superficies, in an almost perpendicular shaft and are supported and guided on side walls of the shaft via their end faces. The roll of material to be stored rests on a stationary, almost horizontal floor. The unwinding roll of material rests on movable supporting elements which are set in motion, during the unrolling of the roll of material, when the latter is supported against supporting rollers forming one end face of the shaft.
