A belt carcass () comprising one, two, or more than two impregnated layers (); characterised in that i) each impregnated layer () comprises, or consists essentially of, a non-woven fabric () and an impregnation material () comprising, or consisting essentially of, a first thermoplastic, first thermoplastic elastomer, first elastomer or first thermoset and optional additives; whereby, if there are two or more such impregnated layers (), they are adjacent to each other, ii) if the belt carcass () comprises one or more such impregnated layers (), then reinforcing filaments extending at least in part in one given direction and being in the form of one filament layer () are embedded in the non-woven fabric () of exactly one of said impregnated layers (); or if the belt carcass () comprises two or more such impregnated layers (), then reinforcing filaments extending at least in part in one given direction and being in the form of one filament layer () are sandwiched between two adjacent such impregnated layers (), and iii) the belt carcass is devoid of woven fabrics. This belt carcass can be cut into longitudinal belts or into circular disks or corner belts.

A sheet material () consisting of an mixture consisting essentially of: a) 10-50 percent by weight of random-oriented fibres, and; b) 90-50 percent by weight of a thermoplastic or thermoplastic elastomer; the weight percentages being based on the overall homogeneous mixture; and the sheet material having at room temperature a Shore D hardness of 40 to 85, preferably of 40 to 60, more preferably of 45 to 55. The sheet material () is used as a support in punching applications or as the top layer in punching belts ().

Continuous treadmill belt comprising a continuous first foamed layer () made of thermoplastic foamed material, with an upper side () and an under side (), wherein a first pulling body () is arranged on the under side () and comprises a first textile layer and a pulling body under side (), and wherein no layer is arranged between the continuous foamed first layer () and the first pulling body (), which hinders a local shearing displacement of the first pulling body () parallel to the under side () or stiffens said pulling body.
