A feed and cutting unit for selectively cutting and dispensing individual weight material segments from a common strip of backing material is disclosed. The feed and cutting unit comprises a feed assembly, a sensor and a cutter member. The feed assembly includes a drive roller and a follower roller that frictionally engages first and second surfaces of a strip of weight material to selectively move the strip of weight material to a cutter member. The sensor is connected to a controller and measures an amount of segmented weight material on the backing material as the strip of weight material moves past the sensor. The cutter member is actuated to separate weight material segments from the backing material by cutting at least a portion of the backing material in a gap disposed between adjacent segments. Weight apply devices that receive the segments for application to an imbalanced member, are also disclosed.

Devices, methods, and systems for splicing a trailing edge of an outgoing roll with a leading edge of a replacement roll with a lapless butt splice on-the-fly during converting and printing production. A first strip of adhesive tape may be placed partially under the leading edge, such that a portion of the adhesive tape remains exposed beyond the leading edge. The replacement roll may be accelerated to match the speed of the outgoing web's movement, a trailing edge of the outgoing web may be cut free from the outgoing roll, and the trailing edge of the outgoing roll may be positioned over the exposed portion of the adhesive tape. A second strip of adhesive tape may be applied over the leading edge and trailing edge using a splicer roller timed to apply the tape when the edges pass proximate to the splicer roller.

A method of joining strip-shaped sheets includes a support step of placing a support member in contact with a reverse feed direction end of a strip-shaped sheet fed to a pressing machine and a feed direction end of a new strip-shaped sheet, and a joining step of joining the new strip-shaped sheet to the strip-shaped sheet by attaching a tape on the reverse feed direction end of the strip-shaped sheet and the feed direction end of the new strip-shaped sheet, wherein in the joining step, the tape is attached from a side opposite the support member with the support member placed in contact with the reverse feed direction end of the strip-shaped sheet and the feed direction end of the new strip-shaped sheet. The problem of the variation in welding quality encountered when welding thin and wide strip-shaped sheets together is resolved and the strip-shaped sheet is fed smoothly.

The splicing device for splicing a trailing edge of a first web material to a leading edge of a second web material includes members defining a feed path of the web material. The device also includes a first cutting member and a second cutting member, cooperating with the first cutting member. One of the two cutting members is provided with a movement transverse to the feed path of the web material, to move the cutting member from an operating position, in which it is in front of the other cutting member, to an idle position, withdrawn with respect to the feed path of the web material.

The present invention relates to the field of SMT splicing belt processing equipment, in particular to a bonding machine for new and old SMT splicing belts, comprising a supporting plate, in which a new splicing belt conveying device and an old splicing belt conveying device which are opposite are arranged on the supporting plate; both sides of the two groups of conveying devices are equipped with limiting blocks which are matched with splicing belts; a jacking device matched with the splicing belts is arranged on the top of the supporting plate; a bonding mechanism matched with the splicing belts is arranged above the jacking device; and the new splicing belt conveying device, the old splicing belt conveying device, the jacking device and the bonding mechanism are connected to a controller. The present invention aims to provide the bonding machine for new and old SMT splicing belts; new and old splicing belts are conveyed to the center through the new splicing belt conveying device and the old splicing belt conveying device, and the new splicing belts and the old splicing belts are bonded and sewed through the bonding mechanism, so that the old splicing belts can be recycled without damaging the splicing effects of the splicing belts, and therefore, the splicing cost is reduced to certain extent.

A method for joining ends of fiber webs with a device comprising a tool element with a gripping device and a traversing punching device. A run of the fiber web from the emptying parent roll is moved to a joining position at the tool element. The trailing end of the parent roll fiber web is cut upstream from the joining position and the fiber web is attached to the tool element by a gripping device of the tool element. An end of a new roll fiber web is guided to contact with and to an overlapping position with the trailing end of the parent roll fiber. The traversing punching device is moved across the width direction of the fiber webs and makes at least one joint cut and joins the fiber webs. The new fiber web is cut downstream from the joint, and then tension control is turned on.
