| titleOfInvention | Apparatus for longitudinal orientation of thermoplastic film material |
| abstract | Apparatus for longitudinal orientation of thermoplastic film material ( 4 ) comprises a width-reduction zone upstream of the longitudinal stretching zone, through which the width of the film is gradually reduced so as to allow longitudinal stretching without necking. The width-reduction zone comprises at least one, preferably several, pairs of pleating rollers ( 16, 17 ) comprising intermeshing grooves or discs for pleating the material, the length of said width reduction zone preferably being less than 3 times the original width of the film. The width-reducing zone has upstream ( 14 ) and downstream ( 15 ) rollers or roller assemblies, with curved axes and optionally also conveyor belts for providing smooth width reduction. Longitudinal stretching is preferably between at least two, and preferably more than two, pairs of stretching rollers ( 9, 10, 11, 12 ) which are relatively close together. The pleats may be provided in several stages with increasing pleats per stage, while guiding means preferably lay all the pleats to one side. The apparatus allows achievement of high tensile strength, yield point, resistance to tear propagation and puncture resistance, especially for polyethylene and polypropylene films. |
