The machine takes use of the principle of reflection and refraction of light to position the cover at the central area, so one can see the position of the book spine clearly. The positioning speed and precision is greatly improved.There is also assistant sucking device under pressure to make the cover flat and not move, so there will be no air bubbles. The cover, cardboard and central spine board can be adjusted and positioned accurately.

1.Center positioning indicator design, to meet customer requirements for binding accuracy, to achieve more accurate positioning
2.The front and rear positioning knob of the cover, so that the cover is fixed into a straight line, to ensure that it is not skewed, to achieve a good covers effect
3.Two suction fan device, so that the cover is better placed horizontally, not upturned
4.Central positioning board design, can adapt to different thickness of books, accurately adjust the thickness of the spine
5.6 scale, 3 different positioning functions, coordinate with each other to ensure the accuracy of positioning and the appropriate size of the book shell
