摘要:
@ A penetrating mechanical roofing fastening and sealing system for securing a flexible sheet, provided with a plurality of apertures, to the upper surface of a roof via the use of a plurality of spaced penetrating fastening and sealing devices, each of which includes upper and lower retainers, wherein the latter are anchored to the roofing surface and the elastomeric sheet is thereafter spread thereover, with cutting portions on the lower retainers being utilized to produce the sheet apertures, rigid upper retainers overlie and completely cover the apertures and the retainers are clamped together in a sealing relationship with the interposed sheet portion. A method for securing and sealing a flexible sheet to the roofing substrate is also presented.
摘要:
In an attachment device, comprising a channel member and an insert member, for securing a flexible membrane within the channel member via the insert member, one of the insert and channel members being capable of deformation to permit the insertion of the insert member, together with adjacent portions of the flexible membrane, into the channel member, the improvement, taking the form of a locking device, insertable into the channel member to prohibit the subsequent removal of the flexible membrane by elastic deformation of one of the channel and insert members.

摘要:
An attachment device for securing a flexible sheet within a channel member via an insert member of generally inverted V-shape wherein the latter is made of a ductile but rigid material having a central longitudinal portion of reduced rigidity that serves to define two adjacent wing portions and permits the subsequent plastic deformation of the insert member into its installed shape after its insertion, together with the flexible sheet, into the channel member. A method for securing the flexible sheet within the channel member, via the ductile but rigid member, is also presented.

摘要:
A tyre (10) produced by way of a moulding or casting process in a manner such that each of its bead areas (16) includes an annular slot (42) whereby the slots permit the insertion of an inextensible annular reinforcement element (40) into each of the bead area slots (42) after the moulding or casting process. Slots (42) are preferably produced by the addition of annular collars (64) to either the outer member (50) or core member (60) of an improved moulding or casting die (48). The improved moulding or casting process includes a step of forming a circumferential slot (42) in each tyre bead area (16), with these slots (42) permitting the addition of an inextensible annular reinforcement element (40) into each bead area (16) after the moulding or casting process.
