Protective-case set and method for packaging a large component

Abstract

A method for packaging a large component into a protective case, which has a first and second reclosable access and a plurality of protective-case parts, wherein the large component has an access opening, comprising the following steps: providing prefabricated protective-case parts; attaching the protective-case parts to the large component; welding the transitions between the protective-case parts; shrinking the protective case; and arranging the first reclosable access in the protective case over the access opening. The packaging process is significantly accelerated compared to the known methods due to the prefabrication of the protective-case parts before the start of the method. Furthermore, the prefabrication provides the advantage that the prefabricated parts can be produced in series. As a result, the protective-case parts for several large components of the same type can be produced or purchased more cheaply.

1 . A method for packaging a large component into a protective case comprising a first and a second reclosable access and a plurality of protective case parts, wherein the large component comprises an access opening, the method comprising:
 preparing prefabricated protective case parts;   attaching the protective case parts to the large component;   welding the transitions between the protective case parts;   shrinking the protective case; and   arranging the first reclosable access in the protective case above the access opening.   
     
     
         2 . The method of  claim 1 , wherein the protective case parts are fixed while being attached to the large component. 
     
     
         3 . The method of  claim 1 , comprising providing the lowest position of the protective case with a draining device. 
     
     
         4 . The method of  claim 1 , wherein the protective case parts comprise films. 
     
     
         5 . The method of  claim 1 , comprising providing a zip fastener as a reclosable access. 
     
     
         6 . The method of  claim 5 , wherein the zip fastener is not arranged until after the shrinking. 
     
     
         7 . The method of  claim 1 , wherein the protective case parts are shrunk as a result of heating. 
     
     
         8 . The method of  claim 1 , comprising arranging a roof covering of rigid material in an overlapping manner as a second reclosable access for a roof opening of the large component, the roof covering comprising a first and a second flap door, and the flap doors forming a passage through the protective case to the roof opening. 
     
     
         9 . The method of  claim 8 , wherein the roof covering comprises seals for sealing the roof opening. 
     
     
         10 . The method of  claim 8 , wherein the roof covering comprises aluminum. 
     
     
         11 . The method of  claim 1 , comprising arranging struts and zip fasteners as a second reclosable access for a roof opening of the large component, the struts connecting different edges of the roof opening and being welded into the protective case, and the opened zip fasteners forming a passage through the protective case to the roof opening. 
     
     
         12 . The method of  claim 1 , comprising, prior to attaching the protective case parts, one or both of attaching an edge reinforcement to the edges of the large component and masking protruding parts on the nacelle. 
     
     
         13 . The method of  claim 1 , comprising dimensioning the pre-fabricated protective case parts such that they do not project beyond the contour of the respective sides of the large component any further than that which corresponds to the capacity of the shrinkage. 
     
     
         14 . The method of  claim 1 , wherein the protective case comprises a bottom cover in the form of a tub-shaped tarpaulin. 
     
     
         15 . The method of  claim 1 , wherein the protective case is flutter-free in the shrunk state. 
     
     
         16 . A protective-case set for a large component comprising an access opening, the protective-case set comprising:
 a plurality of protective case parts from a shrinkable material; and   a reclosable access for the access opening,   wherein the protective case parts are prefabricated and comprise, on their edges, transitions to the respectively adjacent protective case parts of the set such that in the attached and shrunk state, the transitions surround the large component completely.   
     
     
         17 . A protective case for a large component, wherein the protective case is formed from the set of  claim 16  in the shrunk state. 
     
     
         18 . The method of  claim 4 , wherein the films shrink in a biaxial manner.
