Abstract:
A device for cutting a substrate along a cutting line is disclosed. The device includes a saw unit with a saw blade, which can be rotated around an axis of rotation, a guide carriage for moving the saw unit along a guide rail, and a control device for controlling the saw unit and the guide carriage. A marking device is provided for marking an end point of the cutting line.
Abstract:
A turf cutter device, an infill extractor/collector device, and a turf wind-up device are used to facilitate the cost-effective removal of an infilled synthetic turf and the subsequent installation of a new turf at the same site, with minimal subsurface disruption. An infill extractor/collector device mounted on a motorized vehicle moves a relatively narrow strip of filled artificial turf from the surface, in front of the vehicle, and directs the strip to an infill removal station. The infill removal station inverts the strip and redirects the strip back toward the front of the vehicle, after agitating the strip to extract the infill. After redirecting the strip toward the front of the vehicle, the vehicle drives over the unfilled strip. Meanwhile, the extractor/collector device moves the extracted infill rearwardly to a bag located in a trailer. The turf cutter device is used prior to infill extraction, while the turf wind up device may be used before or after infill extraction, depending on whether infill extraction takes place at the field or at a remote site, respectively.
Abstract:
A power saw includes a table configured to receive a workpiece, a saw blade and motor assembly, and a linear guide mechanism operatively connected to the table and being configured to pivotally support the saw blade and motor assembly. The linear guide mechanism enables movement of the saw blade and motor assembly along a predetermined linear path in a forward or a rearward direction at a constant level, and includes a first link and a second link pivotally connected by a first hinge connection. The first and second links enable the linear guide mechanism to maintain the saw blade and motor assembly at the constant level. The power saw further includes a locking mechanism which is fixed to the first hinge connection for locking the linear guide mechanism to prevent the saw blade and motor assembly from being moved along the predetermined linear path.
Abstract:
The invention relates to a cutting device for, in a cutting direction, cutting a belt layer from a web of unvulcanised rubber having mutually substantially parallel cords that are at a cord angle, comprising: a blade which sideward with respect to the cutting direction, is freely movable; a first detector for during cutting detecting a sideward displacement of the +0d5; a control computer, operationally coupled to the first detector, for giving control instructions on the basis of displacement information from the detecting means regarding sideward displacement of the +0d5; at least one actuator, operationally coupled to the control means for during cutting adjusting the cutting direction of the +0d5 on the basis of the control instructions.
Abstract:
A rail-guided power tool (1) has at least one carrying handle (24) and one device head (2) arranged on a guide carriage (12). The guide carriage (12) can be moved by an adjustment mechanism (23) from a locked position—in which the guide carriage (12) is engaged with a guide rail (9) via at least one adjustable guide roller (22)—into a released position—in which the at least one adjustable guide roller (22) is at a distance from the guide rail (9). The power tool (1) also has an unlocking mechanism (25) including an actuator (30), a transmitter (31) and an unlocking device (32), whereby the unlocking mechanism (25) is configured in one piece.
Abstract:
A sheet cutting device includes a cutter holder, a moving unit, and a guide member. The cutter holder accommodates a cutter. The cutter has opposed blades opposing each other to cut a sheet of recording media fed along a sheet feed path of a feed guide plate unit. The moving unit holds the cutter holder and is movable in a sheet width direction perpendicular to a sheet feed direction in which the sheet is fed along the sheet feed path. The guide member is disposed along the sheet width direction to guide the moving unit in the sheet width direction. The cutter holder partially overlaps with the feed guide plate unit in a thickness direction of the sheet perpendicular to both the sheet width direction and the sheet feed direction.
Abstract:
A method and device for installing synthetic turf uses a motorized turf rollout vehicle and a frame removably carried by the vehicle, the frame holding a roll of synthetic turf on a spindle at a first, forward end thereof. The roll and spindle are held in an orientation that is transverse to the first forward direction, and have a transverse dimension that extends beyond that of the vehicle. As the vehicle moves forward in the first direction, the vehicle engages and pulls the roll of turf, and the vehicle also moves on top of the just-unrolled portion of the turf. This accurately and efficiently places the turf on and over the base, in a desired position. Because the vehicle moves on top of the just unrolled section of turf, the present invention eliminates direct contact with, and disruption to, the underlying prepared base. This method and device reduces the time and cost associated with locating a roll of synthetic turf over a base during the installation of an athletic field, compared to prior installation methods.
Abstract:
A powered jamb saw is provided which is ideally suited for making corner cuts. A cylindrical housing for the shaft of the circular saw blade is mounted in a split bushing tensioned by a threaded bolt secured to and for rotation by a handle positioned so as to permit the workman to use both hands to position the jamb saw during its use in making cuts.
Abstract:
Apparatus for cutting an industrial-size roll of paper or other sheet material into two or more rolls. The apparatus includes a circular saw with a radius large enough to cut through such a roll in a single cut, leaving press-ready rolls that require no finish-trimming on the ends. The saw blade is mounted in a saw frame that travels along a carriage and positions the blade at any desired cutting position on the roll. The apparatus includes a support bed and load-bearing arms for supporting the weight of a large roll and keeping it in position during the cutting operation. Load/unload tables and a system of kicking cylinders guide the roll onto and off of the support bed. The saw frame is a tower that positions the saw blade above the roll at the desired cutting position, or a floor frame that positions the saw along side or beneath the roll at the desired cutting position. The apparatus further includes a finishing station for sanding the ends of cut rolls.
Abstract:
A cutter for cutting elongate material into sections, the cutter including a motor coupled to a blade shaft, wherein said motor selectively rotates said blade shaft, a blade mounted on said blade shaft and rotatable therewith, and an actuator adapted to drive said blade along a drive axis toward the material.
