Guide device for the workpiece of a sewing machine |
摘要 |
A guide device for the workpieces on a sewing machine comprises driven guide wheels arranged one above and one below the workpiece, and revolving in a plane extending crosswise to a sewing direction for the workpieces. The guide wheels are each mounted on a low-mass rocker which are, in turn, mounted on a support. Due to the low-mass construction of the rockers, they form together with the respective guide wheels, vibratory systems uncoupled from the respective supports, whereby a uniform frictional contact between the guide wheels and the workpieces is achieved.
