Disclosed are various systems and features for use with a machine, such as a sewing machine, to facilitate 3-dimensional vision systems that may enable operations on non-flat objects and paths. Such systems and features may be useful in the context of performing an action along a self-guided path on a substrate.

A positioning structure for a movable tongue seat includes: an eccentric positioning member disposed between the movable tongue seat and the cutter seat, the eccentric positioning member is provided with a rotary end which is located toward one end of the cutter seat, wherein the eccentric positioning member rotates about the rotary end and is further provided with a drive end which is inserted in a slot of the movable tongue seat, the drive end and the rotary end are not coaxially aligned; and a pivot hole and a pivot provided between the movable tongue seat and the cutter seat, so that the movable tongue seat is able rotate on the cutter seat by rotating about the pivot. When the eccentric positioning member rotates about the rotary end, the drive end can push the movable tongue seat to rotate about the pivot to a desired position.

Due to rapid advancement in computing technology of both hardware and software, the labor intensive sewing process has been transformed into a technology-intensive automated process. During an automated process, product materials may become wrinkled or folded, which can slow down the automated process or result in human intervention. Various examples are provided related to the automation of sewing robots, and removal of wrinkles from products. Images of material on a work table can be captured and analyzed to determine if there are wrinkles or folds in the product. The robot can remove the wrinkle or fold by manipulating the material through the use of end effectors such as, e.g., budgers.

Disclosed is a stapler including: a body including a fixed plate provided on a top portion of one end thereof and formed with a needle insertion hole, and a lower thread supplier provided below the fixed plate to feed a lower thread through the needle insertion hole; and a presser which is connected to the other end of the body at one end thereof by a rotating shaft, includes a fastening needle installed to the other end to stitch an object, and penetrates the needle insertion hole together with an upper thread, in which the object is stitched with the upper thread and the lower thread when pressure is applied to the presser. Since the sheets of paper are bound with the thread, it is possible to prevent the paper from being discolored or crumbed.

A coating apparatus of an airbag reinforcing liquid is used in a sewing machine that includes: a sewing needle driving an upper thread by penetrating sewing target cloth through a vertical movement; and a presser foot disposed above the sewing target cloth, and feeding the sewing target cloth while moving vertically synchronously with the vertical movement of the sewing needle. The coating apparatus includes: a reinforcing liquid supplying part, supplying a reinforcing liquid for reinforcing a sewn part onto the sewing target cloth on a front side from the sewing needle in a feeding direction of the sewing target cloth; and a stamp part attached to the presser foot, and expand the reinforcing liquid supplied from the reinforcing liquid supplying part onto the sewing target cloth around the sewn part by being operated integrally with the presser foot above the sewing target cloth.
