Provided is a method for an optical film which elongates by forming a plurality of sheet pieces by cutting a pre-processing optical film in a width direction of the pre-processing optical film, aligning the plurality of sheet pieces in such a manner that first end portions parallel to the longitudinal direction of the pre-processing optical film are opposite to each other, and connecting end portions of the plurality of sheet pieces to each other.

A wagon (90b) Includes a plurality of horizontal support bars (91f). A separator roll (12b) is stocked while the horizontal support bar is inserted into a core of the separator roll (12b) around which core a separator is rolled. This can prevent deformation and roll misalignment of the stocked separator roll.

Composite structures and methods of forming composite structures may include at least one ply of material extending along a length of the composite structure. The at least one ply of material includes sections of material extending along the length of the composite structure.

A method of cutting a wafer of composite core from a bulk composite core including the steps of placing the bulk composite core in a container, the bulk composite core having a plurality of tube members; depositing a potting compound in contact with an outer surface of the bulk composite core; curing the potting compound; and after curing of the potting compound, cutting through each of the tube members. A method of cutting a wafer of composite core from a bulk composite core, the method comprising the steps of stabilizing the bulk composite core by wrapping an exterior of the bulk composite core with a composite wrap, the bulk composite core having a plurality of tube members; curing the composite wrap; and cutting through each of the tube members.

A floor, wall, or ceiling panel and to a method for producing same. The panel has a base made of a wood material and an upper veneer. The base and the veneer are hot-pressed together while incorporating a resin layer. During the pressing process, pores, cracks, and/or gaps in the veneer are filled with resin. In particular, the pressing process is carried out such that the veneer is saturated with resin, and the resin can be seen on the surface of the veneer after the pressing process. The adhesion of the veneer to the base and the smoothing of the veneer are thus carried out in one operation.

A method of cutting a wafer of composite core from a bulk composite core includes stabilizing the bulk composite core with a fixture, the bulk composite core having a plurality of tube members. The method also includes cutting through each of the tube members to create the wafer while the bulk composite core is stabilized by the fixture.
