A first feed device adjusts an intermittent feed amount thereof based on output of a first sensor such that a design position of a first panel is aligned with a first fixing position during every pause phase of an intermittent feed cycle. A second feed device adjusts tension of a second panel and an intermittent feed amount of a feed unit based on output of at least one second sensor such that a design position of the second panel is aligned with a second fixing position during every pause phase of an intermittent feed cycle. A third feed device adjusts an intermittent feed amount thereof based on output of a third sensor such that the design position of the first panel is aligned with the second fixing position during every pause phase of an intermittent feed cycle.

A sheet product package and method of making discrete plastic sheets includes a package enclosure with a dispensing opening structure and a plurality of discrete plastic sheets arranged in a stack. The plurality of discrete plastic sheets are disposed within the package enclosure, and each of the plurality of discrete plastic sheets is electrostatically charged. In the method of making the dispensable plastic sheets, electrostatically charged discrete plastic sheets are formed and arranged in a stack. The method may include forming a continuous plastic film, cutting the continuous plastic film into discrete plastic sheets, and, after cutting, electrostatically charging the discrete plastic sheets.

An apparatus configured to extend onto and retract from a body of water a flotation mat. The apparatus includes first and second spaced apart support members such that both support members include an upper and a lower end. The spaced apart support members are secured to a boat dock by mounting hardware. First and second vertically slidable members are slidably mounted to the first and second spaced apart support members. The apparatus also includes a rotatable shaft that extends between the upper ends of the first and second slidable members. A sprocket assembly is mounted to one of the ends of the rotatable shaft to facilitate either manual or powered rotation of the shaft for purposes of extending or retracting the mat onto or off the body of water.

According to an embodiment of the present disclosure, a roll-to-roll apparatus may include an unwinding unit, a winding unit, at least one supporting unit, at least one breakage sensor, and at least one holding unit. The at least one supporting unit is disposed between the unwinding unit and the winding unit, and supports the flexible substrate to move from the unwinding unit to the winding unit. The at least one breakage sensor may sense whether the flexible substrate is broken or not. The at least one holding unit may grip the flexible substrate while a breakage of the flexible substrate is sensed by the at least one breakage sensor.

A film winding system (1) for a film stretching unit (110) comprises a film entry area (3) through which a film web (2) to be wound can be fed to the film winding system (1). A first winding station (4) is configured in a winding position to wind the film web (2) into a film bale (5). A contact roller (6) and a measuring roller (8) are provided, the contact roller (6) being arranged adjacent to the first winding station (4) in the winding position and being configured to guide the film web (2) to the first winding station (4). The measuring roller (8) is arranged before the contact roller (6) in the movement direction of the film web (2) and is configured to guide the film web (2) to the contact roller (6). A first adjustment device (10) is provided and configured to move the measuring roller (8) relative to the contact roller (6) along a travel path in such a way that a degree of wrapping over which the film web (2) covers the contact roller (6) can be varied.

A method for detecting irregularities on a material strand made of an elastomeric material comprises the steps of: (a) providing a material strand which defines a longitudinal axis along which the material strand is to be conveyed; (b) bringing a detection element in contact with the material strand, wherein at least one of the detection element being movably mounted in a direction of deflection transverse to the longitudinal axis and a force can act on the detection element in a force direction, (c) setting up a relative movement between the detection element and the material strand along the longitudinal axis; and (d) detecting at least one of a deflection of the detection element in the deflection direction and a force acting on the detection element in the force direction, so as to detect irregularities in the material strand.

An apparatus for unrolling film to a desired length and rapidly cutting multiple sheets of a desired size. The sheets can then be further processed and cut using templates. The system can have a polygonal wheel, an axle slot for receiving a roll of film, a first fastener for attaching the film to the polygonal wheel, a cutter for cutting the film into sheets and a second fastener for forming a stack of sheets of film. The stack of sheets can be further cut with a second cutter into a desired shape.

Disclosed herein is an apparatus for packing articles as well as a device for counteracting winding up of film or web material for an apparatus for packing articles, the packing being formed by at least one web material conveyed over at least one pulling roller, wherein the device for counteracting winding up is disposed in relation to the pulling roller and extending at least partially around the pulling roller, whereby is achieved an easy, secure and functional device that efficiently counteracts and obviates the possibility of web material being wound around a pulling roller.

A device and a method for feeding a sheet material are provided. A conveying machine is disposed above a holding machine. A sensor detects a lateral position of a rubber sheet fed from the holding machine. At a position between a grip position below the conveying machine and a release position at an upstream side in a conveying direction above the conveying machine, a leading edge of the rubber sheet is gripped by a gripping machine. The gripping machine is revolved and moved to the release position using, as a revolution center, a position in a vertical direction midway between the grip position and the release position. The leading edge being released is pressed against a placement surface of the conveying machine by a pressing portion. The rubber sheet is placed on the placement surface and conveyed to a downstream side in the conveying direction by the conveying machine.
