In a machine for forming a hollow body, for example a casing of a solid propellant engine, a tensioned and guided belt comprising a layer of adhesive material and a protective strip is fed from a deposit head, supported by a robot and comprising an unwinding device for unwinding the belt, a winding device for winding the strip, a first pressing roller for pressing the strip and the layer of adhesive material and rotatable about an axis thereof orthogonal to the feed path of the belt and a second pressing roller for pressing the adhesive material and the strip, rotatable about an axis thereof forming an angle other than 90 to the feed path and movable in opposite directions in a direction transversal to feed path.

Liquid dispensing assemblies including adhesive anchoring assemblies configured to adhere to a support surface external to a device such as a vehicle. An air vehicle includes (a) a fluid adhesive container assembly detachably attached to the air vehicle, wherein the fluid adhesive container assembly comprises: (i) an adhesive container comprising fluid adhesive; and (ii) one or more fibers, wherein the one or more fibers are configured, or a brush of fibers, or a fabric of fibers, is configured to conduct the fluid adhesive and to structurally support an adhesive bond between the one or more fibers and a surface; and (b) means for dispensing the fluid adhesive from the fluid adhesive container, to the one or more fibers.

Pusher apparatus and a method of using the apparatus inserts a flexible liner into an in-situ pipe. At least a pair of contra-rotating resilient drive assemblies, having a nip therebetween, drive the liner into the pipe. A guide tube can extend between the drive assemblies and the pipe. A pull head can be affixed to a leading end of the liner and adapted for sealing within a bore of the pipe and pressured fluid can be applied to pull a leading end of the liner into the pipe while the pusher pushes. The contra-rotating resilient drive assemblies can be one or more pair of opposing wheels or opposing tracks. Track assemblies can be mounted to a frame which is movable on rails and restrained with a load cell for measuring reactive forces while pushing. The rails can be angled for aligning the nip with the pipe.

A tape applicator system that employs an extendable arm to carry and control the movement of a tape applicator mounted at its moveable or free end. The tape is dispensed from a essentially fixed location remote from the applicator which permits the use of larger roll (Machine rolls) without the necessitating moving the roll as is required in a normal hand operated device. The movement of the tape applicator mounted on the arm is restricted to straight line movement by the linkage of the extendable arm. If desired a parallel linkage mechanism may be used in the arm to maintain the angular orientation of the applicator which is particularly important when the tape applicator is a common tape head normally use in taping machines. Using a constant height system the height of the tape applicator can be maintained constant when in operation.

Devices, methods and systems disclosed herein relate to the application of a protective film on a surface of an electronic device that instantly reduces air bubbles and eliminates the waiting time usually required when using a wet fluid solution. In one embodiment, a flange may be configured to couple to the protective film. The flange may aid in the accurate application of the protective film to the electronic device.

A roller including a core portion having a cylindrical shape, a support portion located on a central axis of the core portion and configured to rotatably support the core portion, a foam body covering an entire circumference of the core portion and including an outer circumferential surface being flat, an operation portion configured to operate the foam body, and a fixing portion configured to fix the support portion and the operation portion, wherein at least one of end portions of the outer circumferential surface bends toward a direction of the central axis.
