7.5 Automated Tape Laying

Automated tape laying (ATL) is a process that is very amenable to large flat parts, such as wing skins. Tape layers usually lay-down either 3, 6, or 12 in. wide unidirectional tape, depending on whether the application is for flat structure or mildly contoured structure. Automated tape layers are normally gantry style machines (Fig. 7.18) which can contain up to 10 axes of movement. [8] Normally, 5 axes of movement are associated with the gantry itself and the other 5 axes with the delivery head movement. A typical tape layer consists of a large floor-mounted gantry with parallel rails, a cross-feed bar that moves on precision ground ways, a ram bar that raises and lowers the delivery head, and the delivery head that is attached to the lower end of the ram bar. Commercial tape layers can be configured to lay either flat or mildly contoured parts. Flat tape laying machines (FTLM) are either fixed bed machines or open bay gantries, while contour tape laying machines (CTLM) are normally open bay gantries. The tool is rolled into the working envelope of the gantry, secured to the floor, and the delivery head is initialized onto the working surface.

The delivery heads (Fig. 7.19) for both FTLM and CTLM are basically the same configuration and will normally accept 3, 6, or 12 in. wide unidirectional tape. To facilitate the tape laying process, the unidirectional tape purchased for ATL...

Products & Services
Tape Dispensers and Tape Dispensing Machines
Tape dispensers and tape dispensing machines hold and supply tape for assembly or packaging applications.  Dispensing machines can be handheld devices or highly automated robotic systems.
Milling Machines
Milling machines move a clamped workpiece into a fixed, rotating cutter; or move the cutter itself into a stationary workpiece. There are two basic configurations: vertical and horizontal.
Cable Laying Services
Cable laying services install fiber optic cable or copper cable in buildings and office complexes, or over large distances.
Ferrite Beads
Ferrite beads are used to suppress unwanted signals that can interfere with electrical devices such as DC supplies, transmission lines and cables. They provide attenuation of selected frequency bands.
Adhesive Tapes
Adhesive tapes are used to assemble materials or parts together using a sticky chemical bond. Adhesive tapes are made by coating a backing or carrier (paper, plastic film, cloth, foam or foil) with an adhesive on a web or roll coater.
