Part #1 in the Factory Acceptance Test;
The machine in the video above is a Simplex XL-S2 machine (picture of XL-S1) and will be tested for packaging a woodblock with 6-sided-sealing. This will consist of a front- and a back sealing. The packaging sequence must live up to the specified packaging output requirements of the customer.
The proper function of the 2 film stands containing each one film roll will be controlled. This includes that the correct film is being selected depending on the pre-set product dimension recipes which are unique for each product size.
Part #2 in the Factory Acceptance Test;
The purpose of the applied 3D Measuring Bridge which can be seen in the video is to identify the dimensions of the incoming product:
- Height;
- Length;
- Width;
After proper identification of the incoming product, the machine will be notified about this product’s recipe. The recipe contains pre-set parameters in order to execute the packaging process described later in the Step-by-Step guide of RoRo StretchPack.
Part #3 in the Factory Acceptance Test;
Fully automated woodblock packaging solution with full integration between the packaging machine and conveyor system with a 3D measuring bridge installed.

RoRo StretchPack Step-by-Step Guide
In order to understand how the RoRo packaging technology works you can watch this step-by-step guide and gain a fully understanding.
RoRo means
Ro=Roll-on film, Ro=Roll-off film

Which Packaging Machine to Choose?
The RoRo machines all apply the same packaging technology and the selection of an appropriate machine will depend on mainly 3 things:
- Product dimensions;
- Required packaging output / cycle;
- Product variance;
Ad 1 - Product dimensions;
Products within e.g. wood (wood blocks, wood building materials, furniture, panels, tables etc.) and within rolls geotextile, geosynthetics, geomembranes, geofabrics) can typically be covered within the max 8 meter length that is possible with RoRo machines. The maximum height is 1,4 meters and width 1,35 meters.
Ad 2 – Required packaging output /cycle;
The packaging cycles of the Simplex XL machine series are fit to cover most output challenges. So, a wood block of e.g., 6 meters, 0,6 meter high and 1 meter in width can be packed with a cycle of <65 packs per hour based on the length (follow the red arrows in the figure below.). See the cycle information here for XL-S2.
Ad 3 – Product Variance;
An often asked question when we get involved in a new packaging project is: How can the product variance be covered?
The versatility of the RoRo machines makes it possible to cover a variance of products. One film roll can as a starting point cover various product dimensions since the film can be stretched from 0% to e.g. 75%. Products that can fit into this range can be packed with this same film roll.
Now, products outside this range will then need to be covered by a second film roll with other dimensions meaning that we are in S2 solution mode. If this is not enough, we can apply 3 different dimensioned film rolls.
Step-Change in Stretch Hood Machine Design
The founder of Tentoma, Frank Bruhn, has a long track record as service technician at a leading manufacturer of vertical stretch hood machines. This know-how was extended to other vertical stretch hood brands when he started his own technical service company with global reach.
He noticed that the same problems occurred again and again, and this vast know-how was key when developing the new generation of packaging machines based on already proven key technological elements back in 2010. The goal was to eliminate the weak elements he experienced with the vertical stretch hood machines.
Step-Change with RoRo Machine Design
- Opening wedge without any moving parts (avoiding suction cups, etc.);
- Belts and no roller chains (which require maintenance);
- Few moving parts;
- Standard and acclaimed components used (SEW, SICK, FESTO);
- PLC: Siemens Serie 1500 with safety module integrated (programmed in TIA portal);
Product Protection of Outdoor Stored Products 
Tentoma is receiving positive feed-back on the RoRo machines because of the outdoor storage capability of the packed products. The high quality film material applied allows safe outdoor storage of even up to 24 months. The film can be specified with UV protection and UV blocking in order to protect the film and the goods. Besides protecting the goods from moisture, contamination, dust and alike the film also has excellent capabilities in being a low-friction film. When products are stored tightly together it can be a requirement that the film doesn’t get damaged when placing and removing the products.
