Definitions
- U.S. Patent No. 3,562,968 to Johnson et al. discloses a surface treating tool providing for easy installation of the surface treating article.
- the surface treating article has adhered thereto a drive button that engages a complementary cylindrical opening in a drive assembly comprising a back-up pad which is driven by a driving means.
- the adhesively-bonded drive button provides for quick and easy attachment and removal of surface treating elements without special mounting tools.
- the melt-bond obtained by spin welding is primarily obtained by softening the first side 16 of fastener base 12.
- the softened material of the fastener is forced under pressure to penetrate at 22 into a plurality of the interstices 38 of the woven scrim 32. Because the linear speed caused by the rotation of the fastener 12 is greater at the outer diameter of the base 14, the frictional temperatures at the outer diameter are greatest. Accordingly, the material of the fastener is sufficiently softened at the outer diameter portion of the first side 16 of the fastener base 14. This allows the fastener material 22 at the outer portion of the base 14 to bond at least partially around the yarns 34, 36 of the woven scrim 32, and to at least partially penetrate the interstices 38 in the woven scrim.
- the parameters found to affect the strength of the melt-bond between the fastener 12 and surface conditioning disc 30 are as follows. These parameters are provided for a spin weld apparatus 60 having a system inertia of approximately 40 ounce-inches 2 used to fasten the preferred embodiments of the fastener 12 and surface conditioning disc 30 described herein.
- the force that the cylinder 64 applies to the system is preferably between about 125 and 1257 lb. (10 to 100 psi for a 4 inch diameter cylinder), more preferably between about 188 and 628 lb. (15 to 50 psi), and most preferably between about 375 and 628 lb. (30 to 50 psi).
- the speed of the motor 64 is preferably from about 3300 and 5700 RPM.
- the spin time is preferably between about 0.28 seconds and 0.38 seconds.
- the spin time is a measurement of how long the motor 62 is maintained under power from the time the solenoid valve is signaled to apply air pressure for the cylinder to move the fixture 70 and fastener 12 towards the scrim (a travel distance of from approximately 1/8 inch to 13/16 inch), and ends with the command to remove power from the motor 62 after the fastener 12 contacts the scrim.
- a useful parameter for determining a suitable bond strengths is the speed of the motor (RPM) multiplied by the spin time (seconds). It has been determined that this parameter should be above a desired minimum to obtain the desired bond strength. Increasing the parameter beyond the desired minimum shifts the failure mode from release of the melt-bond to breakage of the threaded stud.
