Buckle plates play an integral role in the folding process. They are responsible for ensuring greater quality, shorter set up times, and increased production efficiency. Here’s an insight on the different varieties of buckle plates available for new & Used Stahl Folding Machines.

  1. Small format

This serves as the ideal solution for processing miniature foldings. In fact, it is also capable of processing products having a fold length of just about 35 millimeters.

  1. Buckle plate with swing deflector

This may be used as either a sheet deflector or buckle plate. Thanks to the handwheel, the position and angle of the sheet stop may be adjusted precisely. Even if it is used as a sheet deflector, the sheet stop remains exactly in its position.

  1. Pneumatic Gate fold

This enables print shops to produce a range of three-fold gate fold products. There is the digital control module ACC 2.4, which is responsible for ensuring the exact switching time and pneumatic opening & closing of the deflector profile. Running at a speed of 15,000 cycles per hour, this is the perfect equipment for large run lengths. With the help of spindles, it positions the sheet stop at its precise position, that too with an accuracy of 0.1 millimeters.

  1. Combination

These buckle plates help the print shops to experience shorter set-up times, whilst lessening the burden for the operators. This is possible because the activity of switching from the sheet deflector to the buckle plate may be carried out without moving the buckle plate from the folding machine. They also facilitate carrying out of precise adjustments in the various buckle spaces, such as pre-tension and clearance.

  1. Motor-driven combination

These come equipped with two spindle drives that enable parallel movement of the sheet stop as well as motor-driven corrections of angle and deflector. They also enable storing of adjustments, which may be retrieved at any time in case of repeat jobs.

Die-cutting is a fabrication process which is used to cut, form, and shape rolled metal & sheets. There are several methods of die-cutting, such as flatbed, rotary, laser, and press. The flat bed procedure involves cutting, embossing, waste strip, or blank separation of various types of sheet material. Owing to its high accuracy and precision, this method of die-cutting has gained popularity in the packaging & labeling industries. Flat bed die cutting machines come equipped with cutting, creasing, and engraving attributes. They can either be offline or inline with a printing press. They may also be bought as a stand-alone unit. Here’s an overview of the features of this popular die-cutting procedure:

Materials that can be cut through Flatbed procedure

Some of the materials that can be processed through this method are light papers, boards, plastics, corrugated boards, and some metals.

Industrial Applications

This procedure is widely used in packaging, labeling, and commercial printing industries.

Components of Flat-bed machine

Though each die cutter may have various components based on the application, yet there are some elements that are common to all the machines, such as:

Feeder/ Loader: This section of the unit comes outfitted with suction heads that transport sheet material from the pile to the machine in feed.

In-Feed:  This section is responsible for controlling the movement & transportation of each individual sheet. With the help of mechanical or dynamic registration, the in-feed also registers the sheet material to the cutting tools.

Stripping Section: The stripping section functions as a waste removal unit, which aids in getting rid of internal waste, side, and rear trims. The two tools, upper and lower, work together to remove the excess material.

Blank Separation Section: This tool makes use of dedicated blanking tools to move individual cartons from the sheet material.

Delivery: In the absence of a blank separation section, the delivery creates a pile of full sheets or blanks.

The good news is that this dealer has a ready availability of second hand branded equipment, such as Adast Printing Machine, Heidelberg units, Stahl folding systems, and much more.

Quick Tips for Reducing Delays on an Offset Printing Press

In the offset printing industry, delay accounts for almost 30%, which implies a loss of about one –third of the press time. There are several factors that may trigger a delay, but before discussing that, first, let’s have a look, what exactly constitutes a delay in this industry? It does not comprise makeready or dead time between tasks; rather, it refers to those times when production needs to be stopped for factors that do not pertain to the normal operation of the press. For instance, inadequate maintenance of the machine may result in a mechanical issue, which, in turn, may put the production on hold. Listed below are the most common reasons and their corresponding fixes for delays on new & Used Offset Printing Machines:

  • Web break on start-up

This may occur for several reasons, including, usage of too much or too little water, high blanket, excessive or inadequate tension, and many more. The resolution is simple – provide training to the pressmen so that there is little scope of human error.

  • Running Web Breaks

This is the second biggest reason behind a delay. While some may opine that running web breaks are normal delays and there’s not much that can be done in this aspect, the truth is that these delays can be prevented by providing training to the crew on the subjects of adjusting the infeed according to the paper density & quality, keeping a tab on the tension, and much more.

  • Mechanical Issue due to Inadequate Maintenance

Now, this is the cause of a delay for any machine. It is a known fact that proper preventive maintenance helps in increasing the life of the machine as well as prevents from frequent breakdown. A regular lubrication of an Adast Printing Machine or any other printing press of a reputed brand can go a long way in preventing unnecessary delays.

One should always remember that it’s not just about finding a fix to the problem, but it is essential to identify the root cause of the delay, so that it does not occur again.
