摘要： As a laminated film formed by continuously melt extruding an .alpha.-olefin polymer as a covering film on a traveling, continuous substrate film of an .alpha.-olefin polymer is being cooled by means of a cooling roll contacting the covering film side, pressing rolls are pressed against the laminated film on the substrate film side, along the lateral edge parts thereof, and toward the cooling roll thereby to cause local plastic deformation and thinning of the cover film, which has not fully solidified, due to elastic deflection without appreciably thinning the substrate film, and then the pressing rolls are retracted away from the laminated film, whereby thin-film regions for ensuring positive gripping by tentering clips for lateral stretching are formed along the lateral edge parts.

摘要： This invention provides a drawing machine for pinching and stretching a film-like material of the type having rails installed extending from an inlet section to the outlet section and returning in the opposite direction from the outlet section back to the inlet section of the drawing machine. There is a clip propelling unit moving on the rails for pinching and stretching the film-like material, and elements for generating mutually repelling magnetic fields between the rails and clips, whereby the clips are movable in the non-contact state while floating from the rail guide surfaces. Thus, no foreign substances are generated, cleanliness of products is enhanced, no noise is generated, the work environment is improved, energy is saved, and highspeed operation is attained.
