A hot wire cutting machine. Hot wire cutting machine comprises a heated wire (101); springs (102 and 102a) and grooved rods (103, 104 and 401) supported on end bearings (402 and 403) and optional bearings (404) at middle of the rod (103, 104 and 401) wherein the rod (401) is coupled to a motor 504 for rotating the rod (401) in the direction of wire movement due to thermal effects and achieve minimum rubbing between wire and rod. The composite cutting wire comprises a first wire (1209) which is thicker, braided, high-strength, low electrical resistance joined with a second wire 1201 which is having high-electrical resistance (NiChrome) wherein the first wire (1209) and second wire (1201) are joined by manual twisting/welding and the first wire (1209) is capable of withstanding bending cycles moving over threaded/grooved rod (1203) and oscillated along its length by to-fro rotation of splined shaft (1204).

A cutting device includes: a cutter blade configured to perform one of a half-cutting operation and a full-cutting operation with respect to a cut target; a cutter holder holding the cutter blade; a cutter cradle movable between a half-cutting position and a full-cutting position; and a cutter lever and a cutter cradle lever those operated by a user. When only the cutter lever is operated by the user, the cutter blade is moved so that the cutter blade and the cutter cradle at the half-cutting position perform the half-cutting operation with respect to the cut target. When both the cutter lever and the cutter cradle lever are operated by the user, the cutter cradle is moved to the full-cutting position and the cutter blade is moved so that the cutter blade and the cutter cradle at the full-cutting position perform the full-cutting operation with respect to the cut target.

A cutting device, including a frame, a cutting blade, which is fastened to the frame for pivoting about a first pivot axis, and a reduction transmission, which converts each forward pivoting movement of a plurality of successively performed forward pivoting movements and backward pivoting movements of a drive arm into a cutting pivoting movement of the cutting blade. A cutting-blade back-pivoting apparatus is provided, by which the cutting blade can be pivoted back from a pivoting end position to an initial position. The back-pivoting apparatus has, in particular, a tension element, which acts on the cutting blade in such a way that a clearance is formed.

Aspects of the disclosure relate to an apparatus. In some aspects, the apparatus includes a first arm and a second arm pivotally coupled to the first arm at a hinge. The apparatus further includes a first blade coupled to the first arm and a second blade coupled to the second arm. The first arm and second arm are spaced apart to provide a cavity for receiving sheet material to be cut by the first and second blades. Other aspects, embodiments, and features are also claimed and described.

A packing strap length cutting device includes a main body and a control device. The main body has a first frame and a second frame. A strap pulling unit, a calculation unit and a sensing unit are electrically connected to the control device. The strap pulling unit is connected to a strap connecting unit. Thereby, a packing strap can be automatically pulled out a predetermined length through the strap pulling unit, and then the strap cutting unit is driven by a driving member of the strap pulling unit to cut the packing strap in the predetermined length, assisting a user in completing the cutting operation quickly.

A system and method for stabilizing a substrate during printing of images and subsequent cutting of the printing images with the system. The system comprises a printer assembly and a cutting assembly for printing images on a print media and then cutting the images from the print media. The printer assembly and cutting assembly are positioned in the system such that the media is printed and cut before advancing further through the system. The system has a web feeding system having a plurality of pairs of levers for providing different amounts of pinch force to the web during the printing and cutting processes so as to retain the media in a substantially flat and stationary position for printing as well as cutting.

A borehole is bored to a borehole target depth in a site and a geothermal heat exchanger is inserted into and then secured in the borehole at the desired depth. Once the heat exchanger has been secured in the borehole, the heat exchanger has a closed distal end and an open proximal end and has at least one fluid path between the closed distal end and the open proximal end, with installation fluid disposed in the fluid path(s). After securing the heat exchanger in the borehole and before excavation of a portion of the site immediately surrounding the borehole, the heat exchanger is temporarily sealed by installing, through the open proximal end, at least one respective internal seal in each fluid path. For each fluid path, the internal seal(s) will be disposed below a respective notional subgrade depth and excavation of the site immediately surrounding the borehole can proceed.
