Abstract:
A method for making a tubular device includes coating a first surface of a thin sheet, rolling the sheet such that side edges of the sheet are disposed adjacent one another with the coating disposed inwardly, creating a longitudinal seam along the side edges to create a sleeve, and attaching a tubular structure around the sleeve. In another embodiment, the method includes coating a first surface of a thin sheet, wrapping the sheet partially around a mandrel with the coating disposed inwardly, positioning a slotted tube around the sheet and mandrel, attaching the tube to the thin, and trimming any excess material of the sheet. In another embodiment, the method includes coating an outer surface of a thin sleeve, inverting the sleeve, and attaching a tubular structure around the inverted sleeve, thereby providing a tubular device including a lubricious, hydrophilic, and/or otherwise coated inner surface.
Abstract:
The present invention provides methods of manufacturing a viscoelastic article by a process that includes coating a release surface with a curable composition, contacting a second release surface with the exposed urface of the curable composition and at least partially curing the composition. The composition is then removed from both release urfaces. Viscoelastic articles manufactured according to these methods may be constructed to be self-supporting.
Abstract:
A placement robot having a given positional resolution accuracy positions a component for placement at a selected location on a target substrate. A micro alignment pick-up head (MAP) (20) holds the component. The MAP includes a retention member that may be a vacuum pick-up nozzle (36) and has two main parts: an upper body (22) and a lower body (24). Separated from one another by an air bearing (26). A pressurized gas line to the MAP provides pressurized air to the air bearing. The nozzle (36) with the component attached therefore has a range of motion within the air bearing which exceeds the positional resolution accuracy of the basic placement robot. The MAP may be in one of two states. In the first state the air bearing (26) is disabled, as by inverting the pressure on the air bearing to vacuum, and the upper body and lower body are therefore locked together and move as one. In the second state the air bearing is active and the pick-up head nozzle may be moved freely with no appreciable friction. Micropositioning actuators (58) may be coupled to the MAP's upper body to contact the lower body so as to provide fine positioning in the X and/or Y directions.
Abstract:
A panel of a material is transported in operative proximity to an air knife having a nozzle and a curved Coanda surface, such that the panel is folded over the curved Coanda surface as the material is transported in a machine direction. The panel can be folded to a variety of angles and can comprise a refastenable fastening component. Air knives are employed in various methods for folding garment side panels and forming prefastened garments, such as refastenable pants.
Abstract:
The invention relates to a process for making a tubular cladding hose (20), especially for use in duct rehabilitation work, in which at least one fibre belt is shaped into a curable, resin-impregnated hose. The inside of the cladding hose thus produced is lined with a protective film. It is the purpose of the present invention to provide a process for making a tubular cladding hose in which any lengths of hose can easily be produced. This is achieved in that a strip of film (24) is helically wound around a spindle (1) to make the protective film liner, on which the fibre belt (25) is wound. The invention also relates to devices for implementing the process and the cladding hose itself.
