Welbound 2000 High Speed Perfect Binder
Welbound 2000 High Speed Perfect Binder
 Features Supported :
  • The Book Clamps Travel in an oval shaped path so that the book back is in line with the crucial bindingstations like Milling, Gluing and Cover nipping. (in circular path of motion, the book back is always in tangent to the milling and Gluing stations, resulting in non-uniform milling and gluing across the length of the spine.) 
  • Continuos Flows of clamps to the feed-in stations, with "no book-no cover" safety system. 
  • Variable Speed of Operation (Continuously Variable A/C Inverter Drive) 
  • The Milling station has a specially designed Cutter which removes paper by strips (which has commercial value as waste) and avoids the generation of paper dust. 
  • Three Roller Gluing System (With Reverse spinner) and Separate Side Gluing Tank. Facility for Head and Tail Cut-off of adhesives. 
  • Automatic Cover Feeder (With Creasing attachment) which feeds covers into a Pre-setter where the book back is aligned with cover, before Nipping. 
  • Moving Cover Nipping Station to handle high speeds of operation. 
  • Choice of chute Or Stack delivery System.
     
 Book Clamps :
book clamp

There are 6 Identical Book Clamps provided. One of them can be set according to required clamping pressure by inserting the signatures into the clamp and adjusting a Knob. The calibration provided makes it easy to set the other clamps. While in operation, the signatures are fed manually, one after the other into each clamp. If the signatures are difficult to handle, as in the case of thick books, the speed of machine can be reduced for easy feeding.   

 Milling Station :

The Milling Station is provided with specially designed Milling Cutter and Notching Teeth. The Milling Cutter removes paper in chips/strips form, minimizing the formation of dust. The paper waste is extracted by a powerful Suction device into a Dust Bag. The milling station is protected by Safety Doors. The Milling Cutter can be lowered and disengaged, by a lever, while using the machine for cover pasting Sewn/Stitched books.  

 Hot Melt Gluing Station :

The Gluing Station Consists of 3 Roller Type Applicators. The first Roller penetrates the adhesive into the Notches, the second one builds up adhesive layer along the book spine and the Third, a Reverse Spinner, removes excess adhesive from the spine. A unique Encoder Based System cuts off Adhesive from the Head and Tail end of the book. This results in saving of adhesive as well as avoids unwanted squeeze outs at the Nipping Station. The Tank is heated by 3 Strip Heaters. The temperature is controlled, accurately, through a RTD based Circuit.  

Side Gluing Station :
A Separate Side Gluing Statuion is provided immediately after the Main Gluing Station. The Side Gluing Adhesive can be different from the Spine Glue. (Normally an adhesive of high open time is chosen for side gluing)The temperature is controlled, sepeartely. The Side Glue applicators coat thin layer of both front and back sides and the cover is properly hinged by this.
 Automatic Pile Cover Feeder and Pre Setter :
coverfeeder

The Cover feeder loads from top and feeds from bottom. The lower-most cover is separated from the pile by suction and transferred to a Pre Setter. Covers can be creased On-Line. This Cover is aligned accurately against the Book Block on the Pre Setter, provide immediately after the feeder. The cover will be picked up only if a book is fed into the corresponding book clamp.(No Book - No Cover). If more than one cover is picked up, by chance, the machine is brought to a stop. This avoids wastage of covers.  

 Cover Nipping Station :

A moving type cover nipping station that can handle high speeds of operation, is provided after the Presetter. The Nipping Pressure and the Cover Breaking Pressure can be adjusted to give a perfect Book back.
 

 Delivery Station :
The books are delivered through a Chute Type Tray. Optionally, A stack Delivery system with Conveyor can be provided. If for any reason, the book is not delivered at this stage, the machine will be brought to a stop by the safety switches provided.
