Joint Forming Press

Pressing of cased-in books and simultaneous burning-in of the JOINTS for forming perfect hinge and permanent shape with the help of temperature-controlled pressure blades (Joint Forming Bars).

These blades are spring loaded for adjusting to different depth of joints automatically and hydraulic pressure can be set from 100-300/400kgs to achieve the desired results. The barsĀ  are supplied for Flat and Rounded Spine Book-backs respectively.

Temperature of the blades is set through Digital Temperature Controller (PID) to suit properties of Glue (Adhesive), Binding material and operating speed. The PLC (Programmable Logic Controller) enables choice of single or multiple stroke/s for accurate control of burning-in for maintaining rigidity of theĀ  JOINTS and consistent results. Counter on PLC indicates number of books processed at the end of each cycle.

The system automatically releases the book on completion of the set timing cycle. Back-gauge is provided for faster production. Light Guide indicates the Joint Forming position there by reducing the make-ready time considerably. Adequate operator safety device in addition to Emergency switch incorporated.

PLC based control panel for sequencing, optimum reliability and simplified diagnostics.
