Abstract: Tape layup systems and associated methods. A tape layup system includes a feed spool and an uptake spool. The feed spool is configured to carry a tape roll of tackifier tape that includes a tackifier material and a backing material, and the uptake spool is configured to carry a backing material roll of the backing material. The tape layup system further includes a torque transmission system configured to convey a torque from the feed spool to the uptake spool. The tape layup system is configured such that conveying a torque from the feed spool to the uptake spool operates to draw the backing material onto the backing material roll. A method of operating a tape layup system includes generating tension in a tackifier tape to rotate a feed spool and consequently rotating an uptake spool to draw a backing material onto a backing material roll.

Abstract: Techniques and mechanisms for bonding a first wafer to a second wafer in the presence of a fluid, the viscosity of which is greater than a viscosity of air at standard ambient temperature and pressure. In an embodiment, a first surface of the first wafer is brought into close proximity to a second surface of the second wafer. The fluid is provided between the first surface and the second surface when a first region of the first surface is made to contact a second region of the second surface to form a bond. The viscosity of the fluid mitigates a rate of propagation of the bond along a wafer surface, which in turn mitigates wafer deformation and/or stress between wafers. In another embodiment, the viscosity of the fluid is changed dynamically while the bond propagates between the first surface and the second surface.

The method also includes cutting each continuous blanket of plies into the respective group of charges and stacking the plurality of charges to form the plank stringer.

Abstract: A vehicle is wrapped by an adhesive film which is then slit by applying first tape to the vehicle having a longitudinally extending filament carried by the tape at a position spaced from the side edges.
