In Smyth patented feeder the signatures are transported in a shingled stream by means of geared belts. This unique system reduces by 50% the travelling speed of the signature, compared to a conventional transport of a signature at a time. Contact time with the vacuum openers is longer and the special movement of the suction cups ensures a gentle and precise opening of the signature even in presence of porous paper, heavy perforation and static electricity.The suction cups perform a combined movement
- Forward movement in the same direction and at the same speed of the signatures to increase the contact time with the paper
- Rotation movement to gently open the signature edge
For porous paper, Ventura-type openings are also available.
This exclusive system also differs in the signatures oblique position with respect to their forward direction. Thanks to this position the signature corner, opened by the suckers, can be released on a fixed tile securely. Then, the opened signatures are guided, controlled and transported on the fixed saddle.
The shingled stream transport also outweighs the risks of “flying paper” when signatures are transported at high speed (especially with light paper).
The Integrated Lap Opener increases the versatility of the feeder. It is ready to work when programmed, and does not require any installation. It provides the possibility to open overlapped signatures having different back to front size and different overlap size.Heading up system
Heading up System of signatures consisting of fix header on the tail side and alignment gripper on the head side. This mechanism further ensures the proper transfer of all types of signatures to the sewing head.Kicker wheel
The kicker wheel can be automatically adjusted according to the signature thickness and paper type to allow the optimal feeding of the signature on the mobile saddle.Signature Locking System
The mobile saddle is equipped with a precise signature locking system. This system holds the signatures down on the saddle and assures the exact centering of the stitches on the spine.New pulling out system
The new FF-70 4D comes equipped with a new pulling out system to gently drive the signatures after the sewing cycle.Books delivery
A very compact design enables an easy unloading of the sewn books on the delivery table equipped with a transport system with speed adjustment.Operator interface
Programming and Diagnostics are performed through OMRON PLC and a new software designed by the in-house team of Smyth engineers. A swivel 12” color touch screen is placed centrally to enable all machine functioning parameters and automatic adjustments to be set and checked easily from both sides of the machine.In line connection – OFFSET PRINTING
Smyth FF-70 4D book sewing machine is designed to be connected in line with Smyth gathering machines series P12. In other words, this machine can be purchased as a standalone machine and then connected in line even later.
This is possible thanks to the modular design of Smyth gathering and sewing systems mod. UNIT and CONCEPT.
Even later, Smyth FF-70 4D book sewing machine can also be connected in line with Smyth finishing solutions for digital printing, starting from both flat sheets and reel.

It is the stacker that makes piles of sewn books delivered by the sewing machine in order to facilitate the unloading operations. Pile height is programmable up to 120 mm.Gathering sequence control
The gathering sequence control is a self-learning system performed by Omron Camera which is located in the hopper of the book sewing machine. This camera performs the gathering sequence control by reading shapes (text) and colours. Thanks to continuous measurements this system ensures the highest level of control by filtering data and info, preventing false alarms and unnecessary stops.Pasting device
The pasting device is specifically designed to obtain higher spine book solidity. It is composed of a pneumatic driven gun that applies a thin clod glue strip. It is controlled via touch screen for accurate glue application and simple operation.
The glue system is easy to maintain as it is a self contained pot and does not require daily clean-up of the glue tank.
It is designed to improve reliability of the signature transfer from the feeder to the fixed saddle with any type of signature and any type of paper. This device can be adjusted during the machine set-up, and it keeps the signature open easily.
The FF-70 4D book sewing machine is designed to be connected in line with a Smyth gathering machine series “P12 “.
Thanks to the modular design of Smyth UNIT and CONCEPT gathering and sewing lines, this automatic book sewing machine can be purchased as a standalone machine and then connected in line even later.
The FF-70 4D book sewing machine can also be connected in line with Smyth finishing solutions for digital printing, starting from both flat sheets and reel.
