Problems solved by technology

[0025] Therefore, when the tension of the side yarn 20 is low, the above-mentioned retreat displacement of the passive arm 14 may not be smoothly performed.
At this time, even if the tension of the side yarn 20 is lower than the above-mentioned predetermined value and the tension arm 15 is in a state of retreating and displacing, sometimes the pawl 11 and the ratchet wheel 12 cannot be re-closed immediately, and the side yarn bobbin 52 rotates too much, and the side yarn 20 The tension is also greatly reduced beyond the ideal range

Embodiment Construction

[0055] figure 1Shown is an embodiment of a hemming yarn supply device 1 for a planetary selvedge device on a loom according to the present invention. The side yarn supply device 1, roughly speaking, has: a side yarn bobbin 2 around which a side yarn 20 is wound, a bobbin holder 3 for holding the side yarn bobbin 2 rotatably by a bobbin shaft 4, and a side yarn The tension of 20 is kept within a certain range of tension adjustment mechanism (pawl 11, ratchet 12, driven arm 14, tension arm 15, etc.). In addition, the overall structure of the planetary selvedge device with the side yarn supply device 1 is installed, because it is compatible with Figure 6 The conventional planetary selvage device shown is the same, so the explanation is omitted here.

[0056] The edge yarn bobbin 2 has a cylindrical main body portion 2d around which the edge yarn 20 is wound, and a pair of bobbins 2c formed on both ends of the main body portion 2d to guide the edge yarn 20 . In the axial cente...

Abstract

The present invention relates to a selverdge warp feeding device which is used for a planetary edge weaving device of weaving machine. The aim of the invention is to prevent the damage of selverdge warp bobbin or selverdge warp feeding device, which is caused by the vibration of selverdge warp bobbin in axial direction, etc. In a selvedge warp feeding device (1) which rotatably supports the planetary edge weaving device of the selverdge warp bobbin (2) between a pair of side walls (3a) opposite on a bobbin bracket (3) through a bobbin shaft (4), at least one selected from the end faces 3b and 6b of the selvedge warp, which face a side wall (3a) of the bobbin yarn (3) and an end face 2b that faces the side wall (3a) of the bobbin bracket (3) is provided with a buffer component 5 which projects from the end face of one member to the end face side of the other member.

Description

technical field [0001] The present invention relates to a side yarn supply device for a planetary selvedge device of a loom. Background technique [0002] As shown in Patent Document 1, it is well known that a selvage device as a shuttleless loom utilizes a planetary gear mechanism, which makes two side yarn supply devices rotate while revolving, and performs so-called planetary motion to twist the side yarn. [0003] Figure 6 It is an example of a conventional planetary selvage device, and the hood etc. are omitted in order to show the internal structure of the device. In this device, the carrier gear 8 is rotated by the drive gear 7, and the two side yarn supply devices 51 rotatably supported by the carrier gear 8 are caused to revolve. In addition, the side yarn supply device 51 rotates together with the planetary gear 9 that clamps the planetary carrier gear 8 and is located on the opposite side to the side yarn supply device 51. The planetary gear 9 is flexibly suppor...
