Abstract: Seamed belts, particularly puzzle-cut imageable seam intermediate transfer belts, that have large seam surface areas and puzzle-cut tabs that are resistant to lifting away from the seam. Belts include a substrate having a puzzle-cut first end and a puzzle-cut second end that are interlocked together to form a seam having a kerf. The first end includes a first step and the second end includes a second step. When the ends are interlocked the first step and the second step form a channel. An adhesive is disposed in the channel. The resulting channel beneficially continuously extends along the puzzle-cut seam. When the belt is an imageable seam intermediate transfer belt the substrate takes the form of a semiconductive substrate. Such imageable seam intermediate transfer belts find use in electrophotographic marking machines.

Abstract: A process for providing a seamed flexible polyimide component by providing a poly(amic acid) at the seam between interlocking mutually mating seam elements, and curing the seam, thereby converting the poly(amic acid) into a polyimide adhesive at the seam.

Abstract: Marking machines having imageable seam intermediate transfer belts and toner particles that are “tuned” to that belt. An imageable seam intermediate transfer belt includes a puzzle-cut first end and a puzzle-cut second end that are interlocked along a kerf to form a seam. That kerf has an average width of W. A developer deposits toner particles onto a latent image on a photoreceptor. Those toner particles have an average minimum width (diameter if the particles are spherical) of a size that is similar to W. That is, the kerf width is at least within an order of magnitude of the average minimum width of a toner particle. A transfer station then transfers toner from the photoreceptor to the imageable seam intermediate transfer belt.

Abstract: Seamed belts, in particular puzzle-cut imageable seam intermediate transfer belts and electrophotographic printing machines that use such transfer belts, that are resistant to unzipping. The seamed belts include a first substrate having a first end and a second end that mate to form a first seam that runs across the first substrate. Along at least one side edge of each end of the first substrate is a cut-out. With the first end and the second end mated to form the first seam the cut-outs align to form a larger cut-out. A second substrate is then fitted into the larger cut-out along a second seam. Beneficially, an adhesive is disposed over the first seam and the second seam. Imageable seam intermediate transfer belts have first and second substrates that are beneficially semiconductive and puzzle-cut seams.

Abstract: A seamed flexible belt having a fluoropolymer adhesive and optional fluoropolymer overcoat for use in the xerographic, contact electrostatic, digital and other like machines, the seam having interlocking seam members.
