BELT CUTTER
A portable belt cutting device comprises a cutting head and cutting blade movably arranged on the cutting head. The cutting head has a drive mechanism to move the blade from a retracted position to an extended position, such that the blade severs the belt. The drive mechanism may be coupled to the blade such that the blade is actively driven in both directions between the retracted position and the extended position. In some embodiments, the drive mechanism may comprise a drive spindle which may engage a thread formed in the cutting head. The spindle may be bi-directionally movable and comprise a torque input geometry. In another embodiment the drive spindle and blade comprise connecting elements that form a positive connection when engaged.
DEVICE AND METHOD FOR CUTTING A CONTINUOUS STRIP INTO TIRE COMPONENTS
Disclosed is a cutting device and a method for cutting a continuous strip into tire components. The cutting device includes a knife for cutting the continuous strip along a cutting line in a working plane and a feeding assembly with a feeding member for feeding the continuous strip in the working plane to the knife in a feeding direction that intersects with the cutting line at a cutting angle. The feeding member and the knife are rotatable with respect to each other about a rotation axis perpendicular to the working plane for adjusting the cutting angle. The feeding assembly further includes an input member for receiving the continuous strip in an input direction into the cutting device and one or more guide members for guiding the continuous strip from the input member to the feeding member, wherein the input member is placed in line with or substantially in line with the rotation axis.
AUTOMATIC APPAREL MACHINE
An automatic apparel machine used in the manufacture of air suspension springs has two movable tables that move independently from each other on the rail system and where the raw material is placed. A movable winding mandrel moves up-down and forward-backward on the movable table by a servo motor. Automatic cutting bench grippers are positioned on the automatic rubber cutting bench perpendicular to the axis of the movable tables in the section where the movable winding mandrel is located so as to adjust the lengths of the cut raw material. An automatic rubber cutting bench cuts the raw material in the direction of the length and angles required for the finished product saved in the system.
Handheld belt cutter
A belt cutter for cutting an end portion of a belt having regularly spaced ridges on one side. The belt cutter has a main body with a slot that receives the end portion of the belt. A blade extends from the main body into the slot. A deck having one or more grooves bounds one end of the slot. The grooves receive the belt's ridges and register the belt relative to the blade. A handle is provided to pull the cutter across the width of the belt in a direction parallel to the ridges for the blade to sever the end portion from the belt and form a new butt end parallel to the ridges.
APPARATUS AND METHOD FOR CONVERTING A SHEET INTO A CONTINUOUS STRIP
Disclosed is an apparatus and a method for converting a sheet into a continuous strip, wherein the sheet has a sequence of cuts extending in a cutting direction transversely across the sheet with respect to the longitudinal direction to form a plurality of interconnected sheet sections, wherein the continuous strip has zig-zag sections, wherein the sheet sections are arranged to be pulled apart in a feeding direction to form the zig-zag sections, wherein the apparatus includes a separator device with a retaining device for retaining an upstream sheet section with respect to a consecutive downstream sheet section in the feeding direction and a sensor device for detecting the pulling apart of the downstream sheet section from the upstream sheet section.
Manipulator device having a triangular architecture and installation for manufacturing tires using such a manipulator device for placing strips
The manipulator device includes a pedestal and a carrying mechanism which carries a platform and which forms an articulated triangle comprising: a first arm borne by a first carriage with a first pivot link whose axis forms a first vertex of the triangle, a second arm borne by a second carriage with a second pivot link whose axis forms a second vertex of the triangle, a seat situated at the intersection of the first arm and of the second arm, which forms a third pivot link whose axis is parallel to the first pivot axis and the second pivot axis and forms a third vertex of the triangle. A module is provided for servocontrolling the translational movements of the first carriage and the second carriage with respect to the pedestal. A yaw orientation interface comprises a fourth pivot link, by which the platform is articulated on the seat, both relative to the first arm and relative to the second arm, about a fourth pivot axis which is coaxial to the third pivot axis.
RE-CUTTING DEVICE FOR WIPER BLADES
A re-cutting device for wiper blades has a guide slot (2) conformed to the cross-sectional profile of the wiper blade (W) and having guide rails (2a) that engage with lateral grooves of the base of the wiper blade. A cutting blade (9) for re-cutting the wiper blade edge is arranged in an angled transverse position on a cutting block (7) that is displaceable in the transverse direction between at least two positions in a housing (1), wherein, in the at least two positions, the distance between the guide rails (2a) and the blade region of the cutting blade (9) respectively located in the guide slot region is of different size.
CUTTING STATION FOR A TIRE BUILDING MACHINE
A cutting station for a tire building machine includes a cutting device and a feeding device for feeding a strip of rubber material into the cutting device. The cutting device includes a cutting table for supporting the strip of rubber material in a support plane (P) and a cutting element for cutting the strip of rubber material along a cutting line (C) that extends parallel to the support plane (P), wherein the support plane (P) extends at a support angle (B) with respect to a first vertical plane in a range of five to thirty degrees and wherein the feeding device (5) is arranged for feeding the strip of rubber material onto the cutting table in a downward feeding direction parallel to the support plane. Also provided is a tire building machine incorporating the cutting station and a cutting method.
BELT FORMING SYSTEM
The invention relates to a belt forming system comprises an upstream conveyor (33), a downstream conveyor (32) located downstream of the upstream conveyor, and a belt assembly system in communication with the upstream conveyor and the downstream conveyor. The belt assembly system comprises an arm (52), an actuator for moving the arm (54), and a holding component (53) coupled to the arm and adapted to move a strip section from the upstream conveyor to a desired position on the downstream conveyor such that the strip section is oriented at a predetermined angle on the downstream conveyor. In one embodiment, the belt forming system comprises a belt cutter (42). The invention also relates to a method for manufacturing at least a portion of a tire belt.
Blade mounting structure requiring less current for a heated cutting blade
The present invention provides a method and apparatus of reducing current requirements by increasing resistance of the blade structure by reducing the cross sectional area of at least one section of the blade so that the electrical current requirements for heating of the blade to cutting temperature are reduced wherein the power supply and substantially entire unit may be mounted within a hand held unit. Methods of shaping blades to perform various heat distributions for specialty blades for custom cutting are disclosed. Further, an improved blade mounting structure is provided which includes structure for maintaining the legs of the blade parallel to the direction of cut and provides for easy insertion of new blades by maintaining a slotted blade cradle stable and in alignment with the blades and a clamp member away from the blade when the clamp mounting structure is loosened.
