Abstract
A page binding support tray has vibratory page alignment. The tray has a floor having a lower-most corner at which two side walls of the tray converge. Previously edge-glued printed uniformly sized pages are received to form a stack upon the tray floor and vibration of the tray ensures that edges of the page bear against the side walls of the tray to align the pages prior to edge-pressing.
Claims18
An apparatus comprising:
- a support tray for receiving a stack of printed pages having binding adhesive applied adjacent an edge of at least one of the pages;
- a vibrator interacting with the tray so as to induce vibration therein to assist in alignment of the pages of the stack;
- a press device configured for applying a compressive force to the stack of pages, adjacent an edge of the stack, wherein a support surface of the tray is of adjustable height relative to the press device, so as to ensure that an upper page of the stack is situated at a predefined level for interaction with the press device.
A method of bonding pages in a stack of pages using an apparatus comprising a tray, a vibrator and a press device, the method including the steps of:
- delivering pages one upon another to the tray so as to form a stack of pages, wherein at least one of the pages has binding adhesive applied adjacent an edge thereof;
- during and/or after said step of delivering, inducing vibration in the tray, using the vibrator;
- aligning the pages in the stack, within the tray, by said step of inducing vibration;
- adjusting the height of the support surface relative to the press device, thereby ensuring that an upper pare of the stack is situated at a predefined level for interaction with the press device;
- and
- placing a compressive force, using the press device, on the stack adjacent an edge of the stack corresponding to the edge of the at least one page to which the adhesive is applied, thereby causing the adhesive to bond the pages together.
