DEVICE FOR CHANGING A PILLOW COVER OF A PILLOW

The invention relates to a device for exchanging a used pillowcase from a pillow to a clean pillowcase, wherein the pillowcases are provided with various types of closures, such as a hotel closure.

For example, in the aircraft industry, pillows are often provided with clean pillowcases. After a flight, all cushions are removed from the aircraft and placed in a container, after which the container is brought to a location where the cushions are provided with a clean demolition. There are also other areas where cushions are often provided with clean pillowcases.

The changing of the pillowcases is currently still done manually. This is a very monotonous and repetitive work for people, which is not very motivating.

Furthermore, the disadvantage of manually removing the demolitions is that in some cases the demolitions can sit inside out. When the pillowcases are brought to the laundry, these pillowcases must first be folded back in the correct manner.

It is an object of the invention to reduce or even prevent the abovementioned disadvantages, so that the pillowcases are turned inside out in the right way and to provide a device with which a constant quality can be obtained.

This object is achieved with a device according to the invention, which device comprises: 0 2 4 b 9 7 Η
