    摘要： Disclosed is a two-layer thermoplastic elastomer sheet comprising a skin layer [I] and a reverse surface layer [II], each layer being composed of a thermoplastic elastomer containing a polyolefin resin (A) and an .alpha.-olefin copolymer rubber (B), wherein a difference [(I.sub.B)-(II.sub.B)] between the amount (I.sub.B) of the .alpha.-olefin copolymer rubber (B) contained in the thermoplastic elastomer of the skin layer (I) and the amount (II.sub.B) of the .alpha.-olefin copolymer rubber (B) contained in the thermoplastic elastomer of the reverse surface layer (II) is in the range of 5 to 85 parts by weight. The two-layer thermoplastic elastomer sheet of the invention is excellent in vacuum forming properties and can provide molded products excellent in the soft touch and having appearance of softness, appearance of flexibility and appearance of warmth. The sheet of the invention can be widely used for interior automotive trim such as an instrument panel.

    摘要： An apparatus for looping belt-like materials, including first and second looping units for winding a moving belt-like material helically into first and second coils, with a portion of the belt-like material forming the first coil being drawn out into the second coil. A plurality of support rollers annularly arranged along each of the portions of the wound belt-like material forming the first and second coils, and frames are provided with the support rollers, along with a drive for applying a rotary force to the frames. The support rollers are displaceable in a radial direction of an imaginary circle along which the support rollers are arranged in accordance with variations in diameters of the coils so as to bring the support rollers into contact with the portions of the belt-like material which constitute the coils. The support rollers are annularly arranged along inner circumferential surfaces of the coils, with the drawing of the portion of the first coil being effected by a plurality of small-diameter rollers, arranged along a curved surface of an imaginary cone or cylinder in such a manner that the small-diameter rollers can be rotated in the direction in which the belt-like material is drawn out.
