A bending device for forming a product from a workpiece includes a shaft driven to rotate by a motor, an actuator including an extendable end configured to secure a portion of the workpiece, and a die coupled to the shaft and driven about an axis. The die includes a peripheral portion including a channel configured to receive the workpiece. The channel includes a first end and a second end offset from the first end in a direction parallel to the axis. Rotation of the die about the axis causes the workpiece to bend along the channel.

Provided is an electrode sheet rolling apparatus including: a process unit for performing a rolling or notching process of an electrode sheet, a rewinding unit for winding the electrode sheet finished with the process in the process unit, and a guide roll system which is disposed between the process unit and the rewinding unit and guides the electrode sheet from the process unit to the rewinding unit, wherein the guide roll system includes a plurality of rolls arranged in parallel with each other, and temperatures of the plurality of rolls are set sequentially high along a transfer direction of the electrode sheet.

A flame port structure for burning a gas includes a first continuous spiral strip, a second continuous spiral strip and a first outflow passage. The first continuous spiral strip has a first side edge, a second side edge and a first plurality of annular segments, and the second continuous spiral strip has a third side edge, a fourth side edge and a second plurality of annular segments, wherein each of the first plurality of annular segments and each of the second plurality of annular segments respectively have two first longitudinal opposite surfaces and two second longitudinal opposite surfaces. The first outflow passage has a first defining wall formed on each of the first respective longitudinal surfaces from the first side edge to the second side edge. The first outflow passage is structured so that the gas produces a specific combustion.

A method for the handling of coreless auger, which is produced by an auger production machine from which the coreless auger emerges with a linear motion component and a rotational motion component, includes guiding the rotating auger for linear movement away from the production machine toward a temporary storage facility that has a cylindrical receptacle rotatable about its own axis and a coaxial rotatable feed guide having an axial inlet for formed auger and an outwardly directed outlet for directing formed auger toward an inner periphery of the cylindrical receptacle. The cylindrical receptacle is rotated and the feed guide is allowed to rotate about the axis of its inlet that is roughly coincident with the axis of auger entering the axial inlet of the feed guide. The cylindrical receptacle is rotated at a speed selected to counteract the rotation of the auger about its own axis.
