  • Patent number: 11850765
    Abstract: A cutting apparatus for forming fingers in an end of a belt is provided and includes a blade for cutting the belt and a table for positioning the belt below the blade. The cutting apparatus includes an actuator that is connected to the blade via a primary shaft. The actuator is also connected to the table via both a secondary shaft and a cam assembly. Rotation of the actuator causes the primary shaft to continuously reciprocate the blade in upward and downward directions. Rotation of the actuator also causes intermittent movement of the table that includes both translation of the table to index the belt relative to the blade, and pivoting of the table to change an angle of the belt relative to the blade.

  • Patent number: 10677315
    Abstract: A portable conveyor belt splicing apparatus is provided that includes an upper press assembly and a lower press assembly which include, respectively, upper and lower platen assemblies. The upper and lower press assemblies may each include a forced air cooling system for rapidly cooling platens of the platen assemblies. The upper and lower press assemblies may include insulating assemblies with resilient members that support the upper and lower press assemblies. The resilient members provide structural support and insulate the platens from the frame which reduces the power required to heat the platens. In one form, the apparatus includes a power supply circuit that can alternate between providing power to upper and lower heaters in response to the apparatus being connected to different types of standard power supplies. Further, the power supply circuit permits the use of a single recipe for a particular belt irrespective of the type of power supply.
