A customizable roof drip edge system includes an inner footing, an outer section, and a tail integrally formed with the inner footing and the outer section. The tail is nailable to a roof substrate. The outer section includes a bridging member connecting the tail to an outer footing. The bridging member and the outer footing are configured for directing the flow of water off of a roof. The inner footing is spaced from the outer footing by a suitable distance and configured to be placed against an eave as a positioning aid such that the drip edge can easily and reliably be installed with sufficient spacing for the installation of a fascia board after installation of the drip edge. The drip edge may be bendable to user-selectable angles between the tail and the inner footing and outer section to accommodate a range of roof pitches.

A method of assembling a tapping sleeve includes positioning an outlet band on a pipe element with an arcuate portion of the outlet band contacting an outer surface of the pipe element, the outlet band including a front end, a back end, a first side end, a second side end, a first bend line defined between the first side end and the second side end and extending from the front end to the back end, a second bend line defined between the first bend line and the second side end and extending from the front end to the back end, wherein the outlet band defines an arcuate portion between the first bend line and the second bend line, a first flange defined between the first side end and the first bend line, and a second flange defined between the second side end and the second bend line.

The present invention discloses a manufacturing method of an unequal-torque coil spring and a manufacturing machine thereof for a curtain spring motor, providing a feedback torque that corresponds to an actual requirement from different stages in a curtain-folding working process, so that when the curtain is folded back, the torque can be used to stabilize the speed of folding back the curtain, and the lower beam of the curtain can be fixed at any heights as the curtain is lowered.

A channel bender including: a feeding unit configured to feed and guide a channel material into the channel bender; at least one broaching unit configured to perform at least one of bite broaching and wheeled broaching on the channel material to make at least one broaching mark; and a bending unit configured to bend the channel material that include the at least one broaching mark.

The production method disclosed is a method for producing a front axle beam. The production method includes a die forging step and a bending step. The die forging step is a step of forging a steel material with dies to produce a forged product including a rough web part, which is to be formed into a web part, and four plate-shaped rough flange parts protruding frontward and rearward from an upper side and a lower side of the rough web part, respectively. The bending step is a step of pressing at least one specified rough flange part, which is at least one of the four rough flange parts, with a first die to form a bent portion in the specified rough flange part such that the bent portion is bent inward in an up-down direction of the forged product.

A tapping sleeve includes a first bend line in a planar outlet band between a first side end and a second side end of the planar outlet band, the first bend line extending from a front end to a back end of the planar outlet band, a first outlet flange defined between the first side and the first bend line; a second bend line in the planar outlet band between the first bend line and the second side end, the second bend line extending from the front end to the back end of the planar outlet band, a second outlet flange defined between the second side and the second bend line; and an arcuate portion formed between the first bend line and the second bend line.

A heat exchanger is provided including a first manifold and a second manifold separated from the first manifold. A plurality of heat exchange tube segments are arranged in spaced parallel relationship and fluidly couple the first and second manifold. Each of the plurality of tube segments includes a first heat exchange tube and a second heat exchange tube at least partially connected by a web extending there between. The plurality of heat exchange tube segments includes a bend defining a first section and a second section of the heat exchange tube segments. The first section is arranged at an angle to the second section. A plurality of first fins extends form the first section of the heat exchange tube segments and a plurality of second fins extends from the second section of the heat exchange tube segments.

An arcuate spring having a plurality of coils which are configured and dimensioned to provide an arcuate shape to the spring and being substantially free of internal stresses which would tend to urge the coils into linear alignment. The spring is designed to function under load conditions while maintaining its natural arcuate shape. The spring is can be heated by use of an induction heating process.
