Abstract
An apparatus useful in the assembly of printer cartridges includes a plurality of accumulator bags removeably secured to a carrier sheet. Each accumulator bag includes a first polymer film panel and a second polymer film panel welded together to form a pressurizable chamber with an aperture formed in the bag to provide access to the pressurizable chamber. An annular adhesive element is secured to each bag such that an aperture of the annular adhesive element is generally concentric with the aperture of the accumulator bag. The carrier sheet includes an upper adhesive stripe, a lower adhesive stripe, and a silicone stripe. The plurality of accumulator bags is removeably secured to the carrier sheet by adhering an upper portion of each bag to the upper adhesive stripe, adhering a lower portion of each bag to the lower adhesive stripe, and positioning the annular adhesive element in contact with the silicone stripe.
