Abstract
A needle clamp (1) for sewing machine (100) is provided. The needle clamp (1) comprises a body (2) at least partially made of a thermally conductive material and having retaining means (3) for constraining at least one needle (10). The needle clamp comprises a thermoelectric cooling device (5) directly or indirectly constrained to a portion of said body (2).
Claims16
A needle clamp (1) for sewing machine (100), comprising a body (2) at least partially made of a thermally conductive material and having retaining means (3) for constraining at least one needle (10), wherein the needle clamp (1) includes a thermoelectric cooling device (5) directly or indirectly constrained to a portion of said body (2), said thermoelectric cooling device (5) having a hot side (6) and a cold side (7), said cold side (7) being directly or indirectly constrained to said portion of said body (2) allowing heat transfer from said at least one needle (10) to said cold side (7).
A sewing machine (100) comprising at least one needle clamp (1), said needle clamp comprising a body (2) at least partially made of a thermally conductive material and having retaining means (3) for constraining at least one needle (10), wherein the needle clamp (1) includes a thermoelectric cooling device (5) directly or indirectly constrained to a portion of said body (2), wherein said thermoelectric cooling device (5) has a hot side (6) and a cold side (7), said cold side (7) being directly or indirectly constrained to said portion of said body (2) allowing heat transfer from said at least one needle (10) to said cold side (7).
A method of cooling a needle (10) retained by a needle clamp (1) for a sewing machine (100), said needle clamp (1) comprising a body (2) at least partially made of a thermally conductive material and having retaining means (3) for constraining at least one needle (10), said method comprising the steps of:
- (a) constraining directly or indirectly a thermoelectric cooling device (5) to a portion of said body (2);
- (b) regulating said thermoelectric cooling device (5) to control heat transfer from said needle clamp;
- and
- (c) providing electric power to said thermoelectric cooling device (5).
