A band saw machine has two deflection pulleys arranged one above the other in the vertical direction, an endless saw band, which is guided around the deflection pulleys and which has an upward running portion and a downward running portion, and a machine frame, which has a saw neck for holding at least the upper deflection pulley. The deflection pulleys are arranged substantially parallel to a front edge of the machine frame, so that both the upward running portion and the downward running portion of the saw band face towards the front edge with their cutting edges. The saw neck is arranged offset from the deflection pulleys from the front edge (6) to the rear. Both the upward running portion and the downward running portion of the saw band are at least partially exposed between the deflection pulleys.

A sawmill feedspeed control system having a force sensor operatively coupled to a sawguide of a sawblade, the output of the force sensor being processed and supplied to a motion controller and driver for reducing or increasing feed velocity of a workpiece so as to prevent overfeed or underfeed, while minimizing deviations of the blade from a straight cut and maximizing production throughput.

A food-cutting apparatus has a base; a trolley for placing a food object; a cutting device having two saw wheels, a power source, and a saw belt that is wound around the two saw wheels as a loop. The power source drives the two saw wheels to rotate and further drives the saw belt to circle. The trolley moves the food object so that the food object is cut by the saw belt. The saw belt has teeth oppositely at its two edges. The detector monitors intactness of the teeth and generates a warning signal when determining that any of the teeth is worn. The controlling device cuts off the power source and slows down the trolley when receiving the warning signal.

A method and system for controlling a feed-speed to a bandsaw having a sawblade trained around a drive wheel and a spaced-apart driven wheel, and a strain adjustment mechanism for adjusting the strain on the sawblade by changing the spacing therebetween. The method includes sensing a change in the spacing and making a corresponding change in the feed-speed. The system controls an input device for feeding a workpiece to the bandsaw, and includes a sensor and a controller for performing the aforementioned functions.

A band saw machine for sawing metallic workpieces, having a lower saw part, an upper saw part attached thereto, at least two carrying wheels mounted in the upper saw part, of which at least one is driven, a saw band that revolves with a cutting motion around the carrying wheels and that passes through a cutting region, and a feeding device, attached to the lower saw part, for feeding the workpieces 3 to the cutting region of the saw band and/or into a sawing plane, in which the cutting region of the saw band can be displaced for the purpose of executing a saw advance motion1. The feeding device has a movable holder for detachably fastening the workpiece, such that the holder of the feeding device, starting from an initial position, can be moved both with a translational motion and with a rotational motion to the cutting region of the saw band and/or to the sawing plane. Preferably, the saw band is guided through the cutting region in the same orientation in which it revolves around the carrying wheels, and the holder is moved translationally against the cutting region in order to execute the saw advance motion. For this purpose, the workpiece is preferably turned round by the holder in such a manner that its upper side faces downward.

A material handling apparatus and a process for feed indexing. The process for feed indexing and processing of elongated stock includes the steps of gripping and moving an elongated stock with a first shuttle vise at a desired travel velocity toward a first final position. An open second vise accelerates from a second home start position until reaching the desired travel velocity. The second vise grips and moves the stock once the second vise is at the desired travel velocity while the first vise is gripping the stock. The first vise releases the stock and recycles to a first home position while the second vise moves the stock.

A method and equipment for manufacturing floor underlayment is provided. The equipment is configured to produce floor underlayment having a consistent density and thickness. The equipment has a series of rollers configured to pull a formed batt into a moving transverse blade and to cut the underlayment into two portions having random fiber distribution and even thicknesses and densities.

A hold down mechanism for a bandsaw including an upstream wheel positioned upstream of the saw blade and a downstream wheel positioned downstream of the saw blade, each wheel being rotationally connected to a bogie which is in turn supported on a swing arm. The proximity of the upstream and downstream wheels to the saw blade as well as the degree of pivoting motion permitted by the bogie enable a hold down wheel to press the ends if sequential workpieces against a base as the ends pass the saw blade to assure a uniform thickness of the cut workpiece. An angled guide surface is provide upstream from the forward wheel to assist the forward wheel in elevating when a trailing workpiece is significantly thicker than the workpiece preceding.

A profiling saw with band knife loop take-up and payoff compensation includes an endless circulating band knife which is guided around a plurality of band knife pulleys so the take-up and payoff adjustment is provided of the loop circulation path shape. The take-up and payoff system operates to move a pulley in the vertical plane for allowing the band knife to maintain its cutting orientation during movement and providing for more rapid and precision cuts into a workpiece.

A safety feeder includes a transmission system including a drive shaft having a rotating axis on a phantom axis, and a coupling system connecting to the drive shaft and configured to rotate with the drive shaft simultaneously. The coupling system includes a drive line and a tube covering the drive line. The drive line includes an end thereof connecting to the drive axle.
