needlesSuccess Story

Bread slicers need nowhere in the world in bakeries and supermarkets a shadowy existence of behind inaccessible to customers counter. Because Daub Bakery Machinery BV from the Netherlands offers attractive models in 100 countries around the world, with the help of which customers can share their own bread. For safe, easy operation rotative brakes carry the ACE Shock Absorber GmbH at.

"Would you like to cut it or in one piece?" This question can be asked in many bakeries and supermarkets in the world itself. Because there, the bread slicing machines shown here are increasingly freely accessible to customers, without this at the expense of their safety or sales. On the contrary, relocating from behind the counter to the front of it reduces personnel costs and thus increases the profits of the companies that start them. Sooner or later, it is likely that bread slicing machines like the D-Self Slicer will continue to gain acceptance. The Dutch have been producing innovative baking technology for over 100 years, exporting their products and solutions globally and claiming to be themselves the "tradition of the future". To live up to this credo, they attach great importance to quality, flexibility and design in their own products and those of suppliers. In the production of the D-Self Slicer, they have found a partner with ACE whose products in the damping sector are known for precisely these criteria.

Sharp knives

Perfectly trained and experienced in dealing with bread slicing machines is not a customer. The safety regulations in Germany and the Netherlands therefore place high demands on customer protection. For the developers of the D-Self Slicers, it was therefore part of the specifications that a violation that could be caused by the sharp blades of the automatic machine had to be ruled out. Therefore, as optically clearly recognizable, a hinged protective door was designed. The automatic bread cutting process does not start until the flap is completely closed. The ease of use and the obvious security for each user lead to a reduction of inhibitions and thus to an acceptance by the clientele.

Rotary Dampers protect

ace2A gentle opening and closing of the protective door is important not only for safety reasons in the bread slicing machines - it also ensures that the customers perceive it as pleasant to operate. If the attractively designed hood were pulled up and pulled down too quickly, it would not match the design of the modern do-it-yourself bread slicer with its rounded, symmetrical shapes and different-colored side panels. It was out of the question that the protective door would be slowed down in its end positions by the muscular force of the operator or even open or close with a loud clatter. A dampening solution had to be found that rounded off the successful concept and enabled a guided, harmonious movement. The designers decided to cooperate with the representative of ACE in the Benelux countries, Ralf Küppers. This suggested rotational brakes for integration into the hood mechanism.

The tests were completed quickly, the tests were successful, and so are now rotational brakes from Type FDT57 used in the double-acting bread slicer. In the one-sided version quite similar-looking representatives of the type FDN57 work. The latter differ in that they open and close even more gently than the two-sided models of the type FDT57. In addition to the type of damping, the maintenance-free, ready-to-install machine elements still differ in their braking torque. This is even higher for the FDT brakes at 4,7 Nm and for the one-sided equivalents with 5,5 Nm. The key data are chosen so that even 80% of their maximum power is still sufficient to be able to open and close the protective flap in a harmonious way. Because in both cases, the brakes still have this 50.000% of maximum performance even after 80 cycles. The same applies to both models of the Langenfelder that the power is transmitted to the shaft or pinion and for the opening and closing of the protective cover silicone oil is displaced by a throttle or a gap. The viscosity of the oil and the cross section of the throttle determine the braking torque. If, in other applications, the braking torque during operation be changeable, an adjustment to an adjusting screw is possible.
