Device for assembling a hollow sphere by bonding elements paper- in a flexible material

摘要

The device has spindles (2) forming sphere and comprising tips adhered on two inner polar discs. The spindles are connected with each other at the equator by a flexible strip (3). Two tips of the spindles are extended by other inner polar discs (7). Positioning marks representing form of tips are printed on the discs for facilitating assembling. The spindles are connected to the equator by equatorial glue lug (5).
