Carpet belt

In an automatic pinspotter machine having a carpet belt for conveying pins from the end of the lane to the pin elevator wheel and a motor to drive cylinders on which the carpet belt is mounted, the pin pickup mechanism having a housing surface adjacent the carpet belt, the improvement wherein the carpet belt comprises a soft, flexible elastomeric material capable of being folded on itself while still mounted on the cylinders and capable of embedding a hard metallic object without being torn by the hard metallic object and of firmly wedging the hard metallic object into the space between the carpet belt and the housing surface of the pin elevator wheel whereby substantial damage to the carpet belt is avoided.

In an automatic pinspotter machine having a carpet belt for conveying pins from the end of the lane to the pin elevator wheel and a motor to drive cylinders on which the carpet belt is mounted, the pin elevator wheel having a housing surface adjacent the carpet belt, the improvement wherein the pin contacting surface of the carpet belt comprises a soft, flexible, elastomeric material having a tensile strength of at least about 1,000 lbs./sq. in. capable of embedding therein a hard object without being torn and of firmly wedging the hard object between the carpet belt and the housing surface of the pin elevator wheel.

In an automatic pinspotter maching having a carpet belt for conveying pins from the end of the lane to the pin elevator wheel and a motor to drive cylinders on which the carpet belt is mounted, the pin elevator wheel having a housing surface adjacent the carpet belt, the improvement wherein the pin contacting surface of the carpet belt comprises a soft, flexible, elastomeric material having a modulus of elasticity of about 200% when subjected to a force of about 300 psi capable of embedding therein a hard object without being torn and of firmly wedging the hard object between the carpet belt and the housing surface of the pin elevator wheel.
