摘要： A film stretcher that transports a film material (2) in a predetermined transport direction (A) while holding an end of the film material in a width direction of the film material to stretch the film material in the width direction includes a holding unit (3) that includes a stretching roll (Rl) having an annular groove (11) formed on an outer periphery of the stretching roll and an endless wire (12) fitted in the annular groove over a predetermined rotation angle range of the annular groove in a circular arc shape so that the end of the film material in the width direction of the film material is pinched. The stretching roll is inclined so as to open toward a downstream side in the transport direction of the film material. The holding unit transports the film material in the transport direction while pinching the film material using the stretching roll and the endless wire, whereby the film material is stretched in the width direction.

The drawing roller unit 210 grips a membrane material on both sides in a membrane material width direction, can be inclined so as to spread toward a downstream side in a membrane material carrying direction, and its angle of inclination is variable. The warm air heater unit 100 includes a plurality of cylindrical bodies freely retractably, and both ends are engaged with a first stand 120 and a second stand 130 on both sides in the membrane material width direction. The warm air heater unit 100 expands and contracts in accordance with the angle of inclination made by the drawing roller unit 210, blows out warm air to the membrane material gripped by the drawing roller unit 210, and heats the membrane material.

摘要： PROBLEM TO BE SOLVED: To provide a film stretcher for facilitating thinning of a film without causing stretching unevenness or neck-in.
SOLUTION: In the film stretcher, film stretching is performed by expanding a film material 2 at a holding means 3 side by conveying in one direction while holding the end part in the width direction with the holding means 3. The holding means 3 includes a stretching roll R1 having an annular groove 11 formed on the outer periphery, and an endless wire 12 which is fitted to and inserted into the annular groove 11 in a circular arc shape over the appropriate rotating angle range of the annular groove 11 in a state of sandwiching the end part in the width direction of the film material 2. The stretching roll R1 is obliquely disposed in the direction widening to the end toward the downstream side in the conveying direction of the film material 2, and the film material 2 is extended in the width direction by conveying in the one direction to perform the film stretching while holding under pressure by the stretching roll R1 and the endless wire 12.
