Abstract: PROBLEM TO BE SOLVED: To provide both a tenter clip capable of obtaining a thermoplastic resin film with good productivity, in which physical properties are uniform along the width direction and also thermal dimensional stability and mechanical characteristics are excellent and plane properties are good, and a producing method for the thermoplastic resin film. SOLUTION: The tenter clip is used for stretching in a tenter, a heat tretment process and/or a cooling process. The mechanism of a clip gripping part is changed into such a mechanism that a film is not moved in the longitudinal direction within the clipping part in a stretching process and the film can be moved in the longitudinal direction within the clip gripping part in the heat treatment process and/or the cooling process.

Abstract: PROBLEM TO BE SOLVED: To efficiently mold a resin sheet uniform in thickness. SOLUTION: The average deformation speed ε defined by ε(sec-1)=[ln(D)]/[L /[ V+(V/D)}/2]] [wherein D is a draft ratio (=die lip clearance/average thickness of a resin sheet cooled and solidified on a cooling drum), L is the length (mm) of a molten resin sheet from the die lip to the cooling drum and V is the rotational speed (mm/sec) of the cooling drum] of the molten resin sheet from the die to the cooling drum is controlled with 2-50 sec-1.

Abstract: PROBLEM TO BE SOLVED: To suppress the deflection of a metering bar within a permissible range by constituting a metering unit scraping away the excess supplied coating liquid by freely rotatably circumscribing and supplying the metering bar with two backup rollers and specifying the distance between the centers of rotation of these backup rollers. SOLUTION: The metering unit of the coating applicator including the metering unit for scraping only the excess coating liquid in such a manner that the coating liquid 2 applied on the surface of a web 3 attains a regulated thickness has the metering bar 1 extending in the transverse direction of the web 3. The metering unit has a pair of the backup rollers 4 by which the metering bar 1 is circumscribed and supported. At this time, the distance L between the centers of rotation of the respective backup rollers 4 is so set as to be made smaller than the max. outside diameter D of these rollers 4. As a result, the spacing H between the web 3 and the backup rollers 4 is adequately assured and the exact and precise position adjustment of covers 7, 8 is made possible.
