ABSTRACT:
A deflectable lifting device can be mounted to a support form, work surface or other member of a material conveyance system. According to embodiments, the deflectable lifting device can have a base that mounts into the support, and a bendable arm arranged in the pathway of a material conveyance system, such as a paper stripping or paper blanking work station. When a sheet or web of material travels over the deflectable lifting device, the bendable arm can bend and deflect downwards, but still contact the sheet or web with a gently humped or arcuate portion, providing a small margin of elevation or lift to the sheet or web. The sheet or web can therefore be elevated above edges, holes, or other obstructions in the pathway that could jam or snag the delivery of the material. The deflectable lifting device can comprise an arcuate portion or head over which the sheet or web can slide in a bearing fashion.
