The print industry occupies a position of great importance in any modern industrial society. Even in the age of the Internet, smartphone, SMS and email communication, daily newspapers still account for a major share of transmitting news of all kinds. The production of books, all our works of literature with all the subjects they cover, would be inconceivable without the print industry. Whole stacks of paper are moved on conveyor facilities in a linear direction as well as along curved sections as required. Sometimes, these stacks also have to be turned over while being moved. If conveying along curved sections is required, conical rollers are used. With their help, curves with variable curve radii can also be negotiated within certain limits.
Printing company conveyor belt with special challenges
A mid-sized company manufactures pile turners for the print industry and requires suitable rollers for a feed device. These should be low-maintenance and of a stable design. The special challenges here were due to a non-stop process during heavy load application, which made the use of precision bearings necessary. An additional issue was having to deal with dust occurring during operations. This contract required a complete replacement of the conveyor system with the feeder to be refitted to our rollers. Suitable rollers here are the special series 45 rollers, a welded version with double gear drive Z=12. The tube dimensions for this version are 63.5 x 2.9 mm, with axle design secured and SW. The bearing is sealed on both sides as a 2RS version. The roller bottoms were produced as a recessed version and thus correspond to series 25. This project was carried out using products from our standard range with additional variations. Following coordination and explanation by the technical department, work on the project was started. The time required for the entire conversion of the conveyor system was approx. six weeks.
Rollers for printing company conveyor belt
Series 45 rollers with dual gear drives are suitable for conveying medium to heavy loads. The load capacity of this series is a maximum 100 kg per roller.
In addition to the SW (stands for spanner width) axle design used in this project, other axle versions are available
- IGM (with internal thread),
- M (external thread with hex nut),
- AGM (external thread),
- GL (straight version without thread),
- FA (spring version).
Each axle version has its own features and advantages. Which of these is ultimately the most suitable and selected depends on the particular application involved.
We do not carry out any maintenance work on our rollers and do not offer our customers any service contracts either. We classify rollers as parts subject to wear and tear. In return, we offer our customers preventative warehousing of rollers to ensure their supplies. This assures the customer that there will be no long-term production downtimes due to disruptions, which would be caused by defective rollers.
Many of our customers have been impressed by the quality of our rollers, as they always result in an increase in efficiency and performance in the production process. In some cases, when executing a customer order, it is not necessary to replace an existing conveyor system completely. Sometimes, installing our rollers in the existing conveyor system is sufficient. This kind of solution is of course especially customer-friendly, as the cost involved is reduced considerably. It is also in our interest, of course, to cater to our customer’s requests as far as possible. As such, being as flexible as possible in regard to the entire conveyor system plays an essential role. The conveyor system often has to be usable for all kinds of different products, a concern that is becoming increasingly important.
At TRAPOROL, we provide our customers with performance to the fullest extent. This includes quoting, project management, procurement, and preventative warehousing of quantities requested by customers. These quantities ensure prompt deliveries of replacement rollers and thus prevent possible production losses due to conveyor system downtimes. Our customer-friendly service also includes delivery arrangements with forwarding agents and special packaging to avoid transport damage. Our comprehensive delivery service contributes significantly to our successful business relationships.
