(54) APPARATUS FOR CUTTING LENGTHS OF STRIP MATERIAL
(71) I, ZBIGNIEW JANUSZ SZOMANSKI, a British Subject, of 36 Waldeck Road,
London W.13, do hereby declare the invention, for which I pray that a patent may be granted to me, and the method by which it is to be performed, to be particularly described in and by the following statement : –
This invention relates to apparatus for providing lengths of strip material of a required length.
Items of jewellry after incorporate lengths of light chain and a machine is known for cutting such lengths of chain from a roll of chain. In such a machine there is provided an arm swingable about a pivot with the length between the pivot and the active end of the arm being adjustable.
In use, the arm swings so that a gripping device at the active end of the arm grips the chain; and swings back to an initial position drawing the chain during its swinging motion. A cutter then cuts the chain in a position adjacent to the active end of the arm whereupon the gripping device releases the cut length of chain which drops into a container.
It is an object of this invention to provide an improved apparatus for cutting lengths of strip material which is suitable for use with light chain of the type com- monly used in jewellry.
According to this invention, there is provided apparatus for cutting lengths of strip material comprising a support, mounting means for rotatably supporting a roll of strip material above the support, roller means for drawing strip material from a roll mounted on the mounting means, a motor drivingly coupled to the roller means, said roller means being disposed so that strip material drawn by the roller means can fall under gravity through the plane of the support, further mounting means for carrying, an adjustable distance below the support, a sensor for sensing the presence of strip material, and a cutter carried by the support and positioned to cut strip material after it has passed through the roller means, said cutter means being electrically connected to the sensor and being arranged to cut the strip material when the sensor senses the presence of the strip material.
In use, assuming the machine is used in conjunction with a roll of light chain, the roller means draws the light chain which falls under gravity towards the sensor.
The roller means continues to draw the chain until the sensor senses the presence of the chain whereupon the cutter is activated to cut the chain adjacent to the roller means. The roller means continues to draw the chain until the chain again reaches the sensor whereupon the cutting means is again operated.
It will be seen that the machine will continue to produce lengths of chain which fall from the cutting means into a container or the like until the chain is completely consumed or until the electrical circuit is deactivated.
Preferably, the further mounting means depends downwardly from the support.
A machine designed to cut lengths of light jewellry chain, and in accordance with this invention will now be described, by way of example only, with reference to the drawing accompanying the Provisional
Specification which is a schematic side elevation of the machine.
Referring to the drawing, the machine has a base 1 which is intended to rest upon the floor and supports (by means not shown) a plate 2 horizontally above it.
The plate 2 supports a rotatable roll 3 of chain 4 which is drawn from the roll 3 by a rubber faced drive roller 5 cowoperating with a rubber faced idler roller 6. The drive roller 5 is coupled to a motor 7 mounted on the upper surface of the plate 2.
The roller 6 is urged towards the roller 5 by springs which are not shown. The chain 4 which has passed between the rollers 5 and 6 falls under gravity through a hole to the lower surface of the plate 2. A photoelectric sensor 9 is adjustably mounted on the scale 8 and is electrically connected to a solenoid operated cutter 10 carried by the underneath surface of the plate 2 and posi tioned to co-operate with the chain 4. A vertical tube (not shown) may be secured to the lower surface of the plate 2 for the chain 4 to! fall through but the tube should not extend as far as the sensor 9. Consequently, when the position of the sensor 9 is changed the tube may also have to be changed.
The sensor, instead of being an optical device, may be a magnetic device or may be an eddy current proximity sensor.
Instead of the cutter being operated by a solenoid directly it may be operated through a pneumatic arrangement.
The machine illustrated is suitable for use with aluminium, steel, brass, gold and silver chains.
An electronic counter may be provided and may be settable to any desired number.
The motor, the solenoid cutter, and the sensor may be connected in a circuit with the counter which, after energisation of the circuit, arranges to deenergise the entire circuit when the machine has produced a number of lengths of chain equal to that set on the counter.
WHAT I CLAIM IS: – 1. Apparatus for cutting lengths of strip material comprising a support, mounting means for rotatably supporting a roll of strip material above the support, roller means for drawing strip material from a roll mounted on the mounting means, a motor drivingly coupled to the roller means, said roller means being disposed so that strip material drawn by the roller means can fall under gravity through the plane of the support, further mounting means for carrying, an adjustable distance below the support, a sensor for sensing the presence of strip material, and a cutter carried by the support and positioned to cut strip material after it has passed through the roller means, said cutter means being electrically connected to the sensor and being arranged to cut the strip material when the sensor senses the presence of the strip material.
2. Apparatus as claimed in claim 1, wherein the further mounting means depends downwardly from the support.
3. Apparatus as claimed in claim 1 or claim 2 wherein the support is a plate sup ported on a base.
4. Apparatus as claimed in claim 3, wherein the mounting means, roller means and motor are carried above the plate and the cutter is carried below the plate.
5. Apparatus for cutting lengths of strip material substantially as hereinbefore described with reference to the drawing accompanying the provisional~specification.
**WARNING** end of DESC field may overlap start of CLMS **.

A vertical tube (not shown) may be secured to the lower surface of the plate 2 for the chain 4 to! fall through but the tube should not extend as far as the sensor 9. Consequently, when the position of the sensor 9 is changed the tube may also have to be changed.

3. Apparatus as claimed in claim 1 or claim 2 wherein the support is a plate sup ported on a base.
4. Apparatus as claimed in claim 3, wherein the mounting means, roller means and motor are carried above the plate and the cutter is carried below the plate.
5. Apparatus for cutting lengths of strip material substantially as hereinbefore described with reference to the drawing accompanying the provisional~specification.
