Abstract
A first X-frame (10) comprising first and second pivotally connected elongate members (4 and 5) is pivotally connected to a second X-frame (33) comprising third and fourth pivotally connected elongate members (27 and 28) by means of cross-braces (21, 22, 46 and 47) so that sleeves (11, 12, 36 and 37) pivotally connected to the first ends (6, 8, 29 and 31) of the elongate members (4, 5, 27 and 28) are slidably movable along pivotally interconnected support arms (13, 14, 38 and 39). As the X-frames (10 and 33) move towards each other, the elongate members (4, 5, 27 and 28), the support arms (13, 14, 38 and 39), and the cross-braces (21, 22, 46 and 47) align themselves substantially parallel to each other, the hems of a container (55) of pliable material, which receive the support arms (13, 14, 38 and 39) are gathered together and the container (55) is compressed within the bundle of substantially parallel members.
