"tapered sleeves, which are open at both ends, may be used for flowers in pots and for
protecting yarns for weaving from dust." Figures 1, 2 and 2a each show a pair of
tapered sleeves which are made from two flat sheeting webs and open at both
ends. Figures 3 and 4 each show a pair of tapered bags made from two flat
sheeting webs. The pair of bags shown in Figure 3 are similar to the pair of sleeves
shown in Figure 1 with the difference that each of the narrow openings 14 is closed by a
heat-sealed seam 25, 26. Figures 5 and 6 each show a pair of tapered bags made
from a tubing. Figures 7 and 8 each show a pair of tapered sleeves having curved side
edges and made from two flat sheeting webs. The pairs of sleeves shown in Figures 7
and 8 having two open ends are similar to the embodiment of Figure 2, where two
relatively offset flat sheeting webs having the same width are employed, but the
perforated heat-sealed seam 33 and the lateral seams 34 and 35 formed by severing
and heat-sealing are curved for a more pleasing appearance. As shown in Figures 7
and 8, the curved lateral seams 34 and 35 each have a concave surface and a convex
surface, wherein the concave surface of the lateral seam 34 is substantially opposite
the convex surface of the lateral seam 35 and the convex surface of the lateral seam 34
is substantially opposite the concave surface of the lateral seam 35.
