And along with thick cloth N is further folding, the leading section that folds into plate 61 is directed above thick cloth N, moving.That is, fold into plate 61 when folding into thick cloth N, along with the driving that folds into cylinder 62, by leading section downwards push thick cloth N on one side, proceed to fold into action on one side.
Promptly; In the bar embeded sewing machine 10 of this embodiment, be that the center is supported to swing freely owing to fold into cylinder 62 with the rotating fulcrum 63a of support unit 63, institute is so that fold into plate 61 and can move up and down; Thereby; Even under the situation that folds into thick filler rod cloth N, leading section is advanced sliding freely on filler rod cloth N corresponding to cloth is thick, with cloth fold into reliably base plate 31 above.Therefore, not only under the situation that folds into thin cloth, even under the situation that folds into thick cloth, also can fold into action incessantly.
And, fold into plate 61 and making, before the pin that promptly falls begins, after filler rod cloth N being folded into well and keep, begin to sewing finishing from making, maintain progressive position (pressing position) always, keep the state that filler rod cloth N has been folded into constantly.
(effect of embodiment)
As stated,, can realize and can thick the generation fold into the situation that action stops, and the invagination of the slyness of the thick restriction of the cloth of the filler rod cloth N that is not folded into is moved because of different cloth according to the bar embeded sewing machine 10 of this embodiment.In addition; Because the leading section of doubling entering plate 61 is the side application of force downwards; So can filler rod cloth N be stretched flatly above binder 30 (especially base plate 31), fold simultaneously, thereby the filler rod cloth N that can be implemented in invagination goes up and does not have the lax stabilisation that waits the invagination amount that produces.In addition,, therefore, can realize the reduction of cost owing to do not need to carry out part replacement according to each thick variation of cloth, and the raising of the operating efficiency of this bar embeded sewing machine 10.
In addition, in the action that folds into plate 61, when this leading section that folds into plate 61 contacts with filler rod cloth N, can not stop, even can realize slick and sly invagination action for thick filler rod cloth N because of filler rod cloth N makes to the mobile of direct of travel yet.
In addition, because invagination plate 61 is approaching mobile to oblique below, so can adapt to: the cloth of the scope corresponding with the height change that causes because of moving of leading section is thick.In addition, be that rotate at the center owing to folding into the base end side of plate 61, so can the leading section that fold into plate 61 moved up and down with simple structure with this invagination plate 61.
In addition; In this embodiment, fold into plate 61 and constitute following structure: being supported with support unit 63 through folding into cylinder 62, is that hub head end portion can swing with its base end side thus; But; Also can be for example through elastomers such as spring members such as helical spring and rubber, will fold into plate 61 supportings for parallel mobile about can carrying out, constitute the structure that leading section can be moved up and down thus.
