Abstract
Abstract The invention concerns a binding apparatus to bind loose sheets in covers of which the spines are provided on their insides with a thermoplastic adhesive in order to form volumes, said apparatus comprising a frame with two mutually adjustably spaced rest walls forming an insertion shaft for the covers, said insertion shaft being provided at the bottom with a heating and with a cooling system. To be able to process substantial quantities of volumes to be bound, the insertion shaft 11 is extended at least on one side and the cooling system 20 is received in this extension and a conveyor assembly 27 with revolving drive 30 is provided to move the covers 9 placed into the insertion shaft 11 from the heating system 19 to the cooling system 20.
