Abstract
A marking device performs a marking process onto a long object. The marking device includes a driving source and a marking unit that performs a circular motion in accordance with a driving force supplied from the driving source. While the long object is being transferred, marks are applied onto the long object in accordance with the circular motion of the marking unit. An extent of interference by the marking unit to the transfer of the long object is reduced, thus facilitating higher speed transfer of the long object.
Claims17
A marking device for performing a marking process onto a long object, comprising:
- a driving source;
- and
- a marking unit that performs a circular motion in accordance with a driving force supplied from the driving source, wherein
- while the long object is being transferred, marks are applied onto the long object in accordance with the circular motion of the marking unit.
A marking method of performing a marking process onto a long object, comprising:
- transferring the long object by at least a pair of rolls;
- and
- continuously applying marks onto the long object, while the long object is being transferred, based on a circular motion of a marking unit.
A method of manufacturing a fastener chain in which plural marks are applied along its elongated direction, the method comprising:
- transferring the fastener chain by at least a pair of rolls;
- and
- continuously applying marks onto at least one fastener tape of the fastener chain based on a circular motion of a marking unit.
