1. Pallet comprising base members (1-3) and crosswise members or tubes (4) perpendicularly thereto, especially a disposable pallet, c h a r a c t e r i z e d in that it comprises base members (1-3) made by winding a web material with a surface-coating of glue, the width of which is suitably substantially equal to the length of the base members, around a first spindle, preferably with a rectangular cross section, the height of which corresponds to the diameter or height of the tubes (4), the width thereof being adapted to the width intended for the base member, the said winding being made to a number of turns adapted to the intended structural strength to the formation of a first bobbin (9), and in that subsequently a second spindle has been placed in contact with the lower surface of the first bobbin (9), the dimensions of the said second spindle being such that it together with the said first bobbin (9) essentially completes the inner dimensions of the base member's cross-section, and in that the web material with the surface-coating of glue has been wound around the structure formed by the said first bobbin (9) and the said second spindle a number of turns adapted to the intended structural strength to the formation of a second bobbin (10) enclosing the said first bobbin (9), whereupon the web has been cut and the spindles removed and in that, optionally, recesses (6) for the forks of a fork lift truck have been made in the said second bobbin (10) and in that holes (8) for the said crosswise members or tubes (4) have been made through the two common, opposite, vertical wall sections of the united first (9) and the second (10) bobbin.
2. Pallet according to claim 1, c h a r a c t e r i z e d i n that the said recesses (6) have been made by cutting essentially H-shaped pairs of cuts (11) at the positions for the recesses for the forks of a fork lift truck, whereupon the couples of gluing tongues (12a, b and 13a, b) formed hav been folded inwards and glued to each other.
3. Pallet according to claim 1 or 2, c h a r a c t e r i z e d I n tha the base members therein (1,2,3) on the lower internal surfaces thereof hav been provided with a girder band (14) of a stiff, tensile-strong material glued thereto, which band runs below the gluing tongues (13a, 13b) along the whole length of the base members, the width of said band suitably being equal to the inner width of the base members.

4. Pallet according to cfaFms 1, 2 or 3, c h a r a c t e r i z e d i n that the pallet'rs made of a web material with a thickness within the range 0.2 - 1.0 mm, especially 0.3 - 0.5 mm.
5. Pallet according to anyone of the preceding claims, c h a r a c t e r 5 i z e d i n that the web material comprises polyethylene-coated carton, folding carton, paper or a similar fibrous material.
6. Pallet according to anyone of the preceding claims, c h a r a c t e r i z e i n that the glue applied on the surface of the web material and used for gluing the tongues (12a, 12b; 13a, 13b) is a thermoplastic glue, such

TO as an emulsion glue, optionally boosted with a chelate former.
7. Pallet according to anyone of the preceding claims, c h a r a c t e r i z e d i n that the said first bobbin (9) contains 4 - 8 turns of a carton with a thickness in the range 0.3 - 0.5 mm and that the second bobbin (10) contains 6 - 12 turns.
158. Pallet according to anyone of the preceding claims, c h a r a c t e r - i z e d i n that it comprises crosswise members or tubes (4) made by winding the said web material around a spindle.
9. Base member made as defined in anyone of claims 1 - 6.
