  A process for making hardcover books in a single machine and by hand. The process is divided into three lines, namely book blocks, book covers and sleeves.


  Book core processing flow: semi-finished printed sheet start → hit page → open material → sticky, slip sheet → sticky ring lining → matching page → lock line → semi-finished product inspection → flattening → stacking flattening → cutting book → binding book → coating adhesive ~ →Drying the split→cutting the book→coating the adhesive→rounding→starting the ridge→coating the adhesive→wet→sticking the ribbon→sticking the cloth→applying the adhesive→bonding backing→adhesive backing paper→coating adhesive→sticking Package paper.


  Book sealing process: calculate the size of each material of the book cover → open material → coating adhesive → shell → shell plug angle → flattening → natural drying → hot stamping.


  Casing processing: coating medium seam adhesive → casing → pressure groove → sweeping lining → flattening and shaping → natural drying → finished product inspection → package protection → packaging label.
