A method and an apparatus for producing a container packing filler are provided, which ensure that a net can be correctly and speedily rolled up into a bulk or ball shape. A stretchable tubular net (N) is fitted around a columnar support member (). Then, a distal portion of the net is forcibly folded radially outward or inward by a plurality of roller belts () disposed circumferentially of the net (N), while the roller belts () are moved toward a net proximal side axially of the net (N), whereby the net (N) is rolled up radially outward or inward with the distal portion thereof being forcibly folded by circular rotation and axial movement of the roller belts () to form an annular roll portion (C).

Production method for container packing filler and tubular net rolling apparatus

A container packing filler includes an annular roll portion formed by folding one of axially opposite end portions of a stretchable tubular net radially outward and rolling the net toward the other end portion of the net, and a rigid holder portion provided at the other end portion of the net. The holder portion has sufficient axial length and a width greater than the diameter of a center hole of the annular roll portion so that, when the holder portion of the packing filler is squeezed into the center hole of the annular roll portion, the annular roll portion is expanded from the inside thereof by the holder portion and layers of the annular roll portion are unitarily rolled inward.

Fiber board

The present invention relates to a method of producing a fiber board characterized in that it comprises the following processes (a)&#x2013;(f):

Method of producing a fiber board

A collapsible metal tube, comprising: a metal body portion susceptible of plastic deformation, the body portion being sealed at one end; a shoulder portion and a mouth/neck portion connected to the other end of the body portion; and a resin film provided on the inside wall surface of the body portion, the resin film comprising a metal-adhesive thermoplastic resin layer formed by spray-coating the inside wall surface of the body portion with a dispersion of fine spherical particles consisting of a metal-adhesive thermoplastic resin and then heating to integrate the particles. The resin film formed on the inside of the collapsible metal tube is reliable because it is a dense resin film virtually devoid of pinholes, excellent in elongation at break, and free from cracking when folded or deformed, and is excellent in ability of protecting the metal body portion and the contents.

Collapsible metal tube and aerosol can and method for manufacturing collapsible metal tube

The invention provides a fiberboard, as well as its manufacturing method, which comprises lignocellulose long fibers with a fiber length 50 mm or more and resin. The fiberboard of the invention has high mechanical strength and superior dimensional stability. Since lignocellulose-base materials of long fibers are utilized, the fiberboard can save the consumption of precious wood resources.

A process for peeling a protective film off a thin article such as a silicon wafer is proposed. The film is peeled by sticking an adhesive tape to the protective film on the article and pulling it away from the article. The protective film is peeled only by the adhesive force of the adhesive tape.
