Abstract
A pattern matching sewing machine comprises a sewing means for sewing two superposed sheets of cloth having substantially identical patterns thereon, a feeding means for feeding the two cloth sheets into the sewing means, a detecting means for detecting a mismatch distance between the patterns on the two cloth sheets, and a transport means to transport the two cloth sheets relatively. The pattern displacement amount detected by the pattern mismatch distance amount detecting means may be reduced. A determining means is provided for determining whether pattern matching is possible or not based on the information relating to the mismatch distance obtained by the detecting means.
Claims13
A pattern matching sewing machine comprising;
- sewing means for sewing two superposed cloth sheets, the sheets each having substantially identical patterns thereon;
- feeding means for feeding the two cloth sheets into the sewing means;
- detecting means for detecting a mismatch distance between the patterns on the two cloth sheets;
- and
- determining means for making a determination, according to the information related to the mismatch distance, whether it is possible or impossible to match the patterns on the two cloth sheets.
A pattern matching sewing matching comprising:
- sewing means for sewing two superposed cloth sheets, the sheets each having substantially identical patterns thereon;
- feeding means for feeding the two cloth sheets into the sewing means;
- first detecting means for detecting the pattern of the upper cloth sheet;
- second detecting means for detecting the pattern of the lower cloth sheet;
- calculating means for calculating a mismatch distance between the patterns of the two cloth sheets based on the detection of the first and second detecting means;
- and
- display means for displaying information corresponding tot he mismatch distance calculated by the calculating means.
