In some embodiments, the hemming channel 11 has a main channel portion 11a, a first channel portion 11b and a second channel portion 11c communicating with each other. The bottom plate 13 includes opposite first and

second sides

131 and 132, the first side 131 being curled to form a first channel portion 11b, and the second side 132 being folded to form a second channel portion 11 c. The first channel portion 11b may be used to crimp the edge strip when passing it into the edge channel, the main channel portion 11a being located between the first channel portion 11b and the second channel portion 11c, the main channel portion 11a having side openings 12. The width of the outlet 112 of the second channel portion 11c is greater than the width of the outlet 112 of the first channel portion 11b in a direction perpendicular to the length of the tipping channel 11.

It is understood that the first side 131 is the side of the slide body 1 facing away from the second shelf 3, and the second side 132 is the side facing the second shelf 3. And the length direction orientation of the first channel part 11b, the second channel part 11c, the main channel part 11a and the edge covering channel 11 is consistent, after the edge covering strip enters the edge covering channel 11 from the inlet 111, two sides of the edge covering strip respectively enter the first channel part 11b and the second channel part 11c, one side of the first channel part 11b is curled to form a light-covering pattern, one side of the second channel part 11c is bent to form a scattered edge pattern, and two sides of the edge covering strip wrap the first cut piece. And the part in the middle of the edge covering strip is positioned in the main channel part 11a, and when the first cutting piece extends into the main channel part 11a through the side opening 12, one side of the first cutting piece to be covered with the edge is propped against the edge covering strip. That is, the present embodiment can enable one side of the edge banding to be curled using the first passage portion 11b and the other side of the edge banding to be kept flat using the second passage portion 11c by dividing the edge banding passage into the main passage portion 11a, the first passage portion 11b, and the second passage portion 11 c.

On the other hand, the edge strip wrapping the side edge of the first cut segment can be more smoothly pulled out from the outlet 112. In other embodiments, the first and

second sides

131 and 132 of the slide body 1 may be curled to form the first and

second channel portions

11b and 11c, so that the edge strip is curled on both sides.

It is understood that, the first side 131 is bent to form the first channel portion 11b for curling one side of the edge strip, the width of the first channel portion 11b along the inlet 111 toward the outlet 112 is gradually reduced, and the width of the outlet 112 of the first channel portion 11b can be adjusted according to the actual edge requirement, and the embodiment is not limited in particular. As can be seen from the foregoing, the width of the edge covering channel 11 gradually decreases from the inlet 111 to the outlet 112, that is, the main channel portion 11a gradually narrows from the inlet 111 to the outlet 112, so that the edge covering strips gradually enter the first channel portion 11b and the second channel portion 11b, so as to prevent the edge covering strips in the main channel portion 11a from being too much to cause the edge covering strips in the first channel portion 11b to be insufficient in cloth and unable to curl, and meanwhile, the situation that the edge covering strips coming out from the main channel portion 11a are too much to be stacked and the edge covering strips are not smooth enough can be avoided. Specifically, since the first and

second passage portions

11b and 11c are formed on both sides of the cover plate 14, the width of the cover plate 14 in the direction from the inlet 111 toward the outlet 112 is gradually reduced as the first passage portion 11b gradually approaches the second passage portion 11 c.

Further, the second side 132 is bent toward the curling direction of the first side 131, that is, the first side 131 and the second side 132 are bent and bent in the same direction, and are both bent and bent toward the side of the slide body 1 where the first storage plate 2 is disposed, so that the edge strip can wrap the first cut piece after passing through the edge wrapping channel 11, and not only partially cover the first cut piece. For example, as shown in fig. 3, when the first object placing plate 2 is placed on the right side of the slide main body 1, the first side 131 and the second side 132 are bent and folded toward the right side of the bottom plate 13, respectively, to form the first passage portion 11b and the second passage portion 11 c.
