Sound dampening pad
View Patent ↗An easy to manufacture and install sound dampening pad for a printing blanket sleeve is provided. The pad effectively attenuates noise emanating from the sleeve during air pressurized mounting and dismounting of the blanket sleeve to an underlying cylinder. The sound dampening pad is fabricated from a flexible polymeric material and in one embodiment has a generally J-shaped configuration with inner and outer surfaces. At least a portion of the inner surface of the J-shaped configuration includes a pressure sensitive adhesive thereon to secure the pad to the inner surface of the sleeve.
1. A sound dampening pad comprising a strip of flexible polymeric material having a finite length, a generally curved J-shaped configuration when viewed from an end thereof, and inner and outer surfaces, said inner surface comprising the inner radius of said J-shaped configuration and said outer surface comprising the outer radius of said J-shaped configuration, at least a portion of said inner surface of said J-shaped configuration including a pressure sensitive adhesive thereon.
2. A sound dampening pad as claimed in claim 1 in which said sound dampening pad comprises natural or synthetic rubber or a thermoplastic polymer.
3. A sound dampening pad as claimed in claim 1 in which said pressure sensitive adhesive comprises a double-sided adhesive tape.
4. A sound dampening pad as claimed in claim 3 in which the exposed surface of said double-sided adhesive tape includes a release liner thereon.
5. A sound dampening pad as claimed in claim 4 in which said double-sided adhesive tape includes a foam core.
6. A sound dampening pad as claimed in claim 1 in which said pressure sensitive adhesive is mounted on the longer leg of said J-shaped configuration.
7. A sound dampening pad as claimed in claim 6 in which the shorter leg of said J-shaped configuration has a length such that said shorter leg does not extend to said pressure sensitive adhesive.
8. A sound dampening pad comprising a strip of flexible polymeric material having a finite length, a generally curved J-shaped configuration when viewed from an end thereof, and inner and outer surfaces, said inner surface comprising the inner radius of said curved configuration and said outer surface comprising the outer radius of said curved configuration, at least a portion of said inner surface of said curved configuration including a pressure sensitive adhesive thereon.
9. A sound dampening pad as claimed in claim 8 in which said curved configuration comprises a U-shaped configuration.
