Abstract: The dough-skin folding device contains two or more folding assemblies above a conveyor belt. Each folding assembly contains a base plate and a transmission member beneath the base plate. The transmission member contains pairs of shafts arranged in two rows. Each shaft has a bottom end engaged by a rotatable roller. A pair of the rollers, driven by a power source, makes the other rollers to spin synchronously through transmission belts. A spatula is positioned in front of each folding assembly, and contains a curved blade aligned to the gap between the two rows of rollers. When a dough-skin is moved towards the folding assembles, the dough-skin's lateral sides are scraped up by spatulas and they are folded towards the middle by rollers into a loaf of dough having three layers of dough-skin for subsequent processes. The loaf of dough has multi-level mouthfeel similar to one manually made.

Abstract: Disclosed is an assembly of flexible metal contact bars for a coin-operated path game unit. The assembly includes a fixed supporting block having a rubber-ring-attached shaft frictionally contacting with a driven sliding block having a rubber-pad-attached top. Two electrodes are fixedly attached to the sliding block and extend toward a rotating spiral path in the game unit. When the path game unit is actuated by an inserted coin, the shaft of the fixed supporting block rotates with the rubber ring thereof frictionally contacting with the rubber pad on the driven sliding block to move the sliding block toward the path, so that the two electrodes separately locate above and below the path. The electrode each is formed from at least two metal contact bars flexibly connected to one another by a spring between them, such that the metal contact bar forming a free end of the electrode may bias in any direction to avoid damage when the electrode collides with the path.
