在書籍裝訂中的一種活動式接合，將書板和背襯隔出大約 1/8" 到 1/4" 的間距，可產生空間將封面材料壓入，形成一道凹槽。這是圖書館裝訂中一項重要的特徵，可以使用像是硬布等較厚的封面材料，同時又能輕鬆翻開封面。而「緊密接合」則是將書板後邊緊靠著書肩，形成相當堅固的接合，而無任何凹槽。

緊密接合

英文....	In bookbinding, free-swinging joints produced by setting the boards a slight distance, about 1/8" to 1/4", away from the backing shoulder, creating a space into which the covering material is pressed, forming a gully or groove. It is one of the more obvious characteristics of library bindings. It allows relatively thick covering material, such as buckram, to be used while still allowing the covers to open easily. Distinct from "tight joints," in which the board lies with its back edge flush against the shoulder, making for a comparatively rigid joint with no gully.
荷蘭語....	Een vrij bewegend scharnier dat wordt gebruikt bij het boekbinden, geproduceerd door voor- en achterplat een klein stuk (ongeveer 3 tot 6 mm) van de kneep te plaatsen. Zo ontstaat een ruimte waarin het omslagmateriaal wordt geperst, waarbij er een plooi of een groef ontstaat. Het is een van de meest karakteristieke eigenschappen van bibliotheekbindingen. Er kan op deze manier dik omslagmateriaal worden gebruikt, zoals buckram, terwijl het boek nog steeds eenvoudig kan worden geopend. Anders dan 'gesloten scharnieren', waarbij het plat met de rugsnede tegen de kneep ligt, waardoor een vrij stugge verbinding ontstaat.
