Fabric impregnator (for boatyards and shipyards)
Pro-Set Inc.
Model 892-34 -- The 34" wide, model 892-34 impregnator is intended primarily for the custom builder, using unidirectional materials. Generally, unidirectional reinforcements are used in a 24" to 25" width, so this machine is perfect for these materials as well as woven and stitched materials. Fabric weights up to about 30 oz./sq. yd. can be used in this machine. The hand crank drives one of the nip rollers, and a gear linkage drives the other, so both rollers are positively driven. Roller gap is controlled by an adjustment screw on the roller stop. Adjustable dams in the resin bath and on the nip rollers allow for a range of fabric widths and weights. Narrow tapes and very light fabrics can travel down through a resin puddle in the nip rollers rather than using the resin bath (Figure 1). Light and medium fabrics pass through the resin bath and up through the nip rollers (Figure 2). Heavy fabrics can pass through the resin bath and a resin puddle at the nip rollers (Figure 3). The rollers open to make it easy to load and clean.
Fabrics can follow several different paths on each model to accomodate a range of fabric weights. configuration for very light fabrics configuration for light and medium fabrics configuration for heavy fabrics
The weight of the fabric and the viscosity of the resin system determine the throughput of the machine. For example, a 24" wide, 9 oz. unidirectional S glass can be wet out at about 15 feet per minute, with a resin content of 40 to 45% by weight using the PRO-SET Epoxy 145/229 combination.
Model 892-60 -- The mechanical and physical characteristics of the model 892-60, 60" wide impregnator are the same as the 34" machine, but the dimensions are enlarged proportionately to handle a wider range of fabrics. This model is intended primarily for the custom or small production builder, particularly those using wide woven and stitched fabrics up to 60" wide and as heavy as 40 oz./sq. yd.
