Method for producing hoods and arrangement of a plurality of hoods
The invention relates to a method for producing hoods in the form of hair nets having meshes, creating hoods having a first dimension over the head from front to rear and a second dimension crosswise thereto. A strand ( 20 ) of a net having a mesh ( 23 ) is created from threads ( 21 ). The strand ( 20 ) has two longitudinal sides. The number of meshes ( 23 ) of the net crosswise to the longitudinal sides corresponds to the number of meshes ( 11 ) of the hair net to be produced along the first or second dimension of the hair net. On or neighboring the two longitudinal sides of the strand ( 20 ), one elastic thread ( 22 ) each is fed into the outer meshes ( 23 ) of the net. At specified, regular distances, the two elastic threads ( 22 ) are guided together and connected to one another. The distance is chosen such that the number of meshes ( 23 ) of the net between two connection points ( 24 ) in the longitudinal direction of the strand ( 20 ) corresponds to the number of meshes ( 11 ) of the hair net to be produced along the first or second dimension of the hair net. The two elastic threads ( 22 ) are connected by joining to one another by means of a sealing and/or melting process. A weakness ( 25 ) is introduced in the connection region ( 24 ).
1. A method of manufacturing and using a hood arrangement comprising the steps of:
providing a plurality of unseparated hoods that are formed into a chain at a manufacturing site;
constructing the plurality of unseparated hoods at the manufacturing site having two common elastic threads that pass through and which are guided in each of hoods through meshes in the peripheral region of the respective hoods;
constructing and arranging said plurality of unseparated hoods together to form said chain with every two adjacent hoods of the plurality of hoods being joined together at a joining region;
forming the joining region by a melting or bonding process of the two elastic threads with one another, which form surrounding edge threads, the joining region forming a weakness between every two adjacent hoods;
the step of constructing the plurality of unseparated hoods at the manufacturing site including all the hoods being unseparated and formed in one of a continuous roll and accordion arrangement;
providing a use site wherein the hoods are used by the application to the head of a subject; and
separating the chain into individual hoods at the use site, different from the manufacturing site;
said separating step being between adjacent hoods at the joining region by means of a breaking at the joining region at the weakness.
2. The method according to claim 1 , including providing the elastic threads constructed as covered threads.
3. The method according to claim 2 , including providing the covered threads as comprised of a core thread of a material that has a melting point that is 10° C. or more, particularly 30° C. or more, higher than the material of the threads of the net forming the meshes and of the material of the threads used for the covering.
4. The method according to claim 1 , including providing the elastic threads as a thermoplastically fixed, particularly spiral-shaped, coiled polyamide.
5. The method according to claim 1 , including forming the weakness by a perforation.
6. The method according to claim 1 , including forming the weakness by a constriction line crosswise to the longitudinal direction of the chain of a plurality of hoods.
7. The method according to claim 1 , including forming the threads of the net from a polyamide or a polypropylene.
8. The method according to claim 1 including forming the joining region as a constricted joining region having a width substantially less than a hood width at the two common un-joined elastic threads, and forming the weakness at the constricted joining region.
9. The method according to claim 8 including forming the weakness by one of a perforation and a constriction line crosswise to the longitudinal direction of the chain.
