Why use a Pile Turner ?
Originally the machine was used just for turning paper, to replace manpower by machinery. Nowadays it fulfils many more additional tasks, such as
- Airing - Dust removing - Drying - Aligning - Jogging -
For the demands of the printer or paper and board converter a pile turner with these capabilities represents an indispensable piece of equipment
The Busch pile turner speeds up and improves both the printing and the finishing process. Different sorts of paper and board with varying weights can be handled on the turner. As the demands for quality increase, the pile turner represents a sensible investment.
In 1976 the first Busch pile turner was designed and delivered. With decades of experience a perfect engineering is guaranteed - and top quality is Buschs first priority. The solid and modern designed machines are well known for their easy handling they are used worldwide and prove a notable longevity.
All Busch pile turners are designed and manufactured in own factories in Germany (Seevetal). The large range of models, with numerous options, fulfils all individual requirements.
Functions of the Pile Turner
Pile turners are available just as a turning unit or with airing and aligning, and with the additional option of jogging. The following pages on this website give detailed information of all available models and options.
Turning easy and comfortable
Turning is done by hydraulically lifting the pile to the horizontal position and subsequently rotating it through 180°. It replaces time-consuming manual handling.
Airing what can be achieved ?
-
Dust removing -
An important process before printing to achieve better print quality - absolutely essential for the board converter. -
Separation of cutting edges -
To avoid mis-feeds. The complete pile is filled with an air cushion between the sheets. -
Conditioning -
The pile is provided with the optimum temperature and humidity. -
Removal of spray powder -
Removal of surplus spray powder after printing an advantageous process for finishing. -
Drying -
Ink and varnish is quickly dried after printing. Heat inside the pile is reduced. -
Odour neutralizing -
Important for food packaging. -
Airing with ionised air
Ionisation reduces the electrostatic charge which may affect the finishing process of coated and printed paper or plastic foil.
Aligning the pile
The pile is aligned against the aligning gauge in the tilted position with high volume airing. Bad sheets can be removed without a problem depending on the thickness of the material.
Jogging
The ideal support to speed-up perfect alignment of the pile - in the tilted position with high volume airing.
Centreing the pile
The pile can be centrally aligned on a larger-sized pallet without problem.
Preferences of a Busch Pile Turner
Two model series are available
- With decades of experience, Busch guarantees perfect engineering
- Top quality modern design
- Large range of model variations
- Embedding in the floor or fixing to the floor is unnecessary
- An optimal hydraulic system (counter torque lowering valves) and a powerful airing system
- Blowers for the airing system are integrated in the machine body
- The platforms allow the use of all sorts of transport and machine pallets.
- Loading and unloading is made from the wide side
- The clear aluminium control desk can be fitted on either side
- The control desk is slewable (on turners with airing) which facilitates the control at the front and rear of the pile during airing
- Models equipped with pressure control flaps ensure that the pile is not compressed, so that the air cushion is preserved in the pile important for finishing printed sheets!
- Individual control of air jets (at the control desk)
- Regulation of air jet speed (at the control desk)
- The optional equipment with ionised air reduces the electrostatic charge of paper and plastic foil
- The integrated programmable logic controller (PLC) enables automated airing processes and hydraulic functions as well as a clear fault diagnostic at the display (on all turners with airing)
-
Pile turners of SWH series with airing include pressure control flaps as standard. The aligning gauge is adjustable according to sheet width and pile height. The jogging intensity is adjustable at the control desk. Air jets are travelling just under the respective pile height. Alternatively it is possible to pre-select the number of air jet travels (start and stop) to enable an airing process without the presence of an operator
Taking into account all possible options - a wide spectrum is achieved for processing paper and board with extreme variations in quality.
The Busch pile turner speeds up the printing and finishing process
The press can run permanently at high speed
The pile turner needs less than 1 minute for turning a pile
and 4-5 minutes, on average, for turning, airing and jogging the pile
Any employee can operate the pile turner
