They are found on both sides of the cover and were made to assist the easy opening of a case-cover by sharing the hingeing movement required of a cover with the joint crease. A cover opened to 180\u00b0 with only spine creases will make the cover material hinge through 180\u00b0 along one narrow line, subjecting the cover to a great deal of stress. By adding joint creases, the movement is shared, with each crease only hingeing through 90\u00b0, thus reducing the strain on the cover.","type":"string"},"datatype":"string"},"type":"statement","id":"Q388$B5B2CF1B-A998-4BED-A32A-483EE2A8FF8E","rank":"normal"}],"P440":[{"mainsnak":{"snaktype":"value","property":"P440","hash":"e7ad996d67f7467c1895ca47208e5a22fabbbf70","datavalue":{"value":{"entity-type":"item","numeric-id":703,"id":"Q703"},"type":"wikibase-entityid"},"datatype":"wikibase-item"},"type":"statement","id":"Q388$73EA5FB7-F181-4FD9-9CB9-4A9389CD71FB","rank":"normal"}],"P426":[{"mainsnak":{"snaktype":"value","property":"P426","hash":"9e1333355bcff875e31344ea0d0deb81f898f88e","datavalue":{"value":{"entity-type":"item","numeric-id":196,"id":"Q196"},"type":"wikibase-entityid"},"datatype":"wikibase-item"},"type":"statement","id":"Q388$D8EE1CFF-A2FC-470E-ADB6-FC7C708D0872","rank":"normal"}]},"sitelinks":{}}}}
