lateral movement by the action of the frictional force between the conforming outer surface of pad 14 and the flat surface on which catcher 10 is located pad 14 also absorbs vibrations and noise emitted from the serger during operation thus pad 14 provides lateral stability which helps prevent vibration a motion of the base 12 during serger operation as greater weight or force is placed against planar section 22 pad 14 will compress until edge 31 contacts the flat surface at which point both pad 14 and perimeter wall 30 support planar section 22 and the weight or force thereon pad 14 is attached to the underside of planar section 22 with an adhesive 34 preferably a pressure sensitive adhesive attached to pad 14 pad 14 with the adhesive area exposed is pressed against the underside of the planar section 22 and the adhesive 34 will bind pad 14 thereto although pad 14 may be placed over the entire underside of planar section 22 except that area adjacent and within aperture 16 pad 14 is preferably disposed only in the portion of pad recess 32 over which the serger will be placed which is further described herein referring again to fig1 and 2 aperture 16 is a rectangular section having flange 18 and bag 20 retained therein aperture 16 is bounded by aperture wall 36 which is a wall projecting downward from planar section 22 having a rectangular perimeter a flange recess 38 in the form of a right angled lip is disposed between planar section 22 and.
