An extruding unit, a forming roll unit and a thick portion forming mechanism are provided. The extruding unit has an ejecting slit which ejects sheet-shaped molten resin. The ejecting slit includes a standard gap portion and an enlarged gap portion. The standard gap portion is formed as a gap having a constant size. The enlarged gap portion is formed as a gap larger than the standard gap portion in a position corresponding to a thick portion. The thick portion forming mechanism forms one or several thick portions which are thicker than other portion, in the sheet-shaped molten resin continuously in the extrusion direction.

A foam sheet includes a composition containing an aliphatic polyester resin, and the foam sheet has a surface roughness Sa (i.e. arithmetic average height) of 81 μm or higher.

Provided is a molded surface fastener capable of stably having high engaging strength with respect to a loop member. The molded surface fastener of the present invention includes a base portion and a plurality of engaging elements provided with a stem portion and an engaging portion, and is formed of synthetic resin containing lubricant at 0.15 wt % or more and 1.00 wt % or less. A top end surface of the engaging element is formed to be flat, and the engaging portion has a hanging portion which hangs down obliquely downward toward the base portion.

Aspects disclosed herein relate to forming on a substrate fastener elements suitable for use in touch fastener by employing vibration forming methods. The processes described provide for a greater flexibility in manufacturing than prior methods and overcome certain limitations in prior forming techniques. Further, the product made can embody a variety of different configurations suitable for a given application. Employing vibration forming methods, such as ultrasonic forming methods, allows for the use of a wider variety of substrate material than materials used with convention methods of touch fastener formation.

A double belt press has at least one press device having at least one pressing plate and at least one counter-pressure element for the pressing plate each other. Portions of first and second endless and driven metal belt belts are guided, opposite one another, through a press gap located between the pressing plate sides facing one another and the plate-shaped counter-pressure element. The press device has at least one pressing stamp having a pressing surface movable toward the counter-pressure element and back again. The first and second endless metal belt portions guided through the press gap are guided between the pressing surface of the at least one pressing stamp and the at least one counter-pressure element, and the pressing surface of the pressing stamp is smaller than a surface of the side of the at least one pressing plate facing the at least one counter-pressure element.
