摘要:
The invention relates to anti-skinning agents containing mixtures of organic compounds (combinations of additives), whereby the organic compounds are selected from the groups of organic hydroxylamines, and &bgr;-dicarbonyl compounds and/or selected derivatives of formic acid and also relates to compositions containing them, especially oxidatively drying paints or coating compositions.

The invention relates to a process for preventing skinning of a coating composition comprising adding an anti-skinning agents containing mixtures of organic compounds (combinations of additives), whereby the organic compounds are selected from the groups of organic hydroxylamines, and β-dicarbonyl compounds and/or selected derivatives of formic acid to the coating composition.
摘要:
The invention concerns hydrous compositions based on polychloroprene and hydroxylamine derivatives, processes for their production and their use as adhesives. The polychloroprene dispersions are stabilized by the addition of hydroxyalkylamine after removal of residual monomer.
摘要:
An apparatus for pressing a cover onto a printing material block that is moved in a transport direction has a first pressing element that can be moved in a first direction and one or more second pressing element that can be moved transversely to the first direction. The first pressing element, in particular, is a pressing table moving in the vertical direction and the second pressing element one or two pressing rail(s) that can be moved in the horizontal direction. The apparatus has a drive unit, in particular with a servo motor, to which a variable control profile can be applied via a connection to a control unit. The variable control profile allows the movement of the pressing rails, for example their stroke or the course of their stroke, to be adapted to the current processing job. The apparatus is particularly suited for use in adhesive binders.

A book binding machine includes a collating machine, a perfect binder and a transfer device disposed between the collating machine and the perfect binder. The collating machine and the perfect binder are actuated by a common control device. In each case, one transport segment is assigned to a respective book block clamp by the control device. The control device also has a program which, if a defective or missing book block clamp is detected, actuates the collating machine in such a way that no book block is collated for that book block clamp. A method for operating a book binding machine is also provided.

A method of driving a gathering stapler having a plurality of subassemblies including a stapling carriage, a collecting chain, a stapling-displacement configuration, a delivery, and an ejector. The method includes separately driving at least two of the subassemblies, each with a separately controllable drive. Commanding movements of the subassemblies driven in each case by controllable motors, with an electronic control unit. Synchronizing a movement of one separately driven subassembly with a movement of at least one other separately driven subassembly. Executing a variable collecting-chain movement adapted to a simultaneous operation of the stapling carriage.

A gatherer stitcher having a gatherer chain configuration includes roof segments forming a ridge region and drivers having respective stop surfaces and being mounted so as to be adjustable between an operating position and a position pivotable away therefrom. An auxiliary driver is restricted to the ridge region and carried by a respective roof segment directly adjacent the stop surfaces. The auxiliary driver, in the operating position of the adjustable driver, forms a combined stop surface together with the adjustable driver.
