Abstract

993,618. Flexible tubes. G. PASQUETTI. May 7, 1964 [May 11, 1963], No. 19149/64. Addition to 983,261. Heading F2P. In the flexible tubular body described in the parent Specification and comprising a strip-like element of a synthetic plastic wound helically so that a shank 2 is inserted into a slot of a boxlike portion 1 to interlock the convolutions of the element, spaced apart holes 31 are provided in the shank so that the body may be used as a hot air duct, or for irrigation or land drainage.
