Thank you Natthawat.
The glue you see on the double spider is the silicone adhesive that is used to join the two single spiders together.
It’s perfectly ok that some silicone pass through the spiders’ cloth; the quite large quantity of silicone used is necessary to reach the required mechanical strength and avoid any delaminating effect.
Hope this helps to clarify this matter.
Best regards,
