Description
IMPROVED FRENCHING DEVICE AND METHOD OF USE
TECHNICAL FIELD
Described herein is an improved Frenching device and method of use. More specifically, an automated
or semi-automated device is described to produce a so called ‘French rack’ or ‘Frenched rack’ with
intercostal tissue substantially removed from the bone by the device.
BACKGROUND ART
Frenched racks and their production are described in detail in the applicant’s patent, NZ585885, the
contents of which are incorporated herein by reference.
Summarising, the most common way to produce a Frenched rack currently is manually or by hand. On
average, a skilled butcher can French up to six racks per minute. Depending on the number of butchers
employed for this purpose, the labour cost of manual Frenching can be very significant. The hand
process also introduces inherent vagaries of manual cutting including minor variations between cuts,
fatigue and potential for injury.
One automated art solution is described in the applicant’s earlier patent which is a high pressure water
based spray to remove intercostal tissue from between the bones. This method is effective but poorly
accepted in industry as use of water can introduce microbes and therefore be detrimental to product
shelf life and hygiene.
The applicant’s patent NZ585885 describes a ‘punching’ method of Frenching using an automated
device.
A manual form of stripping in order to produce a French rack identified by the inventors involves initially
cutting the intercostal muscle with a knife parallel to the ribs and then tightly wrapping string around an
individual rib at the desired Frenching depth. The string is then quickly pulled toward the rib tip thereby
removing the meat from the rib bone and leaving a clean bone.
The methods and devices noted above provide options for Frenching however other methods may also
be possible or at least offer the public a choice as described further herein.
Further aspects and advantages of the improved Frenching device and method of use will become
apparent from the ensuing description that is given by way of example only.

Frenching utilising stripping functionality to remove intercostal tissue between rack bones.
In a first aspect there is provided a device for Frenching a rack, the device comprising:
(a) at least one retention means that at least partially retains at least one meat cut incorporating
rack bones and intercostal tissue between the rack bones; and
(b) at least one stripping member that interacts with intercostal tissue in the rack;
and wherein, in use, the at least one stripping member acts to at least partially strip the intercostal tissue

DETAILED DESCRIPTION
As noted above, described herein is a Frenching device and method of use, the device comprising an
automated means of Frenching utilising stripping functionality to remove intercostal tissue matter
between the rack bones.
For the purposes of this specification, the term ‘about’ or ‘approximately’ and grammatical variations
thereof mean a quantity, level, degree, value, number, frequency, percentage, dimension, size, amount,
weight or length that varies by as much as 30, 25, 20, 15, 10, 9, 8, 7, 6, 5, 4, 3, 2, or 1% to a reference
quantity, level, degree, value, number, frequency, percentage, dimension, size, amount, weight or
length.
The term ‘substantially’ or grammatical variations thereof refers to at least about 50%, for example 75%,
85%, 95% or 98%.
The term 'comprise' and grammatical variations thereof shall have an inclusive meaning - i.e. that it will
be taken to mean an inclusion of not only the listed components it directly references, but also other
non-specified components or elements.
The term ‘stripping’ or grammatical variations thereof refers to a process of mechanically tearing tissue
from bone as opposed to cutting the tissue from the bone.
The term ‘Frenched rack’ or ‘French rack’ grammatical variations thereof refers to a cut of meat derived
from the a rib bone of a rib rack of an animal carcass, the meat cut at least partially comprising a rack
and, when in a finished form, the meat cut has at least part of the intercostal meat removed between
the rib bones. The process of producing a French rack is termed ‘Frenching’ or to ‘French’. The meat cut
without Frenching may be termed the ‘loin’. The term ‘rack’ refers to the rib cage and associated meat.
The applicant’s patent NZ585885 describes a Frenched rack in more detail, the contents of which are
incorporated herein by reference.
In a first aspect there is provided a device for Frenching a rack, the device comprising:
(a) at least one retention means that at least partially retains at least one meat cut incorporating
rack bones and intercostal tissue between the rack bones; and
(b) at least one stripping member that interacts with intercostal tissue in the rack;
and wherein, in use, the at least one stripping member acts to at least partially strip the intercostal tissue
from the rack bones.
In a second aspect, there is provided a method of Frenching at least one meat cut, the method
comprising the steps of:
(a) selecting a device substantially as described above;
(b) at least partially retaining a portion of at least one meat cut incorporating rack bones and
intercostal tissue between the rack bones via at least one retention means;
(c) engaging the intercostal tissue between the rack bones with at least one stripping member; and
(d) operating the device so as to force the at least one stripping member along the rack bone
length away from the retained portion of the meat cut thereby stripping the intercostal meat
from the rack bones.
The inventors have identified that mechanical punching of intercostal tissue from rack bones may not be
ideal. Specifically, punching requires a high degree of precision in where the punch is made in order to
achieve the desired level of tissue removal. The reality is that in a working environment, achieving this
accuracy may be difficult, particularly where a fine tolerance in sensing may be critical. Unexpectedly,
the process of stripping tissue from the rack bones has proven surprisingly effective in removing the
intercostal tissue.
Stripping as noted above refers to the process of mechanically tearing the tissue from the bone or bones.
Tearing may refer to the tissue (mainly muscle/meat) being torn from the bones breaking the connective
tissue between the meat/muscle and bone. The inventors have found that this interface fails at a
defined force, the force not being so high as to also break the bone or bones – that is, the connective
tissues fails before bone breakage.
The at least one retention means may be a clamp or clamps that hold part or all of the backbone portion
of the meat cut and/or part or all of the rib bone or bones. The clamp may for example be at least one
movable pad, plate, rod or bracket that compresses down on a part of the meat cut, retaining the meat
cut between a fixed pad/plate/rod/bracket and the movable pad/plate/rod/bracket. The clamp as a
whole may be stationary and the stripping member or members move relative to the clamp/retention
means. Various art retention means already exist that may be incorporated into the device and methods
described herein. The retaining means may hold only part of the meat cut. The retaining means may not
interfere with the meat cut bone or bones and intercostal tissue. This may be important to allow the
stripping action to occur.
The at least one stripping member may have a shape that enables the intercostal tissue to be pierced,
gripped or otherwise retained so as to provide interference between the at least one stripping member
and the intercostal tissue. In one example, the at least one stripping member or a part thereof may
include a sharpened point able to pierce through a section of intercostal meat and, in doing so allowing
the stripping member or a part thereof to abut the intercostal tissue in preparation for stripping
movement. Alternatively, the at least one stripping member may grip the intercostal tissue via a
mechanical linkage. In a further alternative, the at least one stripping member may frictionally abut one
or both sides of the intercostal tissue.
The location of piercing, gripping or other engagement of the intercostal tissue may be approximately
half-way between bones. The inventors have found that the accuracy is not that critical in that some
variation from the true mid-point in the intercostal tissue may be tolerable without failure of the
stripping process further described below. This lower accuracy requirement provides a significant
advantage over the applicant’s earlier punching process where accuracy was of more importance to
ensure the intercostal tissue was punched and not the bone or bones.
As noted above, the at least one stripping member may be moved to a point enabling interference with
the intercostal tissue. The at least one initial position of interference may be located towards the
backbone end of the rib bone. The exact position may be determined by the preferred length of exposed
bone dictated by consumer preference. The exact length of exposed bone may be important to
determining the final product value hence this initial position of interference may be important.
At this point, the at least one stripping member may be drawn away from the backbone portion of the
meat cut and towards the bone ending. The drawing action may be approximately in-line with the bone
direction although, as may be appreciated, bone direction may not be straight – rib bones are generally
curved and hence the direction of drawing may also vary. The extent of drawing direction variation may
for example change based on bone length, animal species and so on. This drawing action in the
inventors’ experience, effectively tears the connective tissue from the bone and, when drawing is
complete, substantially all of the intercostal tissue may be removed from the bone.
The drawing force may be pre-set. As may be appreciated a drawing force that is too high may break
bones resulting in product rejection or drop in value. Alternatively, a reduced force may not be sufficient
to tear the intercostal tissue from the bone. In the inventors experience, a force of 50 to 600N may be
sufficient to achieve both objectives noted however this should not be seen as limiting since the force
needed may vary depending on meat cut size, bone length, animal species and so on. The force may be
50, or 75, or 100, or 125, or 150, or 175, or 200, or 225, or 250, or 275, or 300, or 325, or 350, or 375, or
400, or 425, or 450, or 475, or 500, or 525, or 550, or 575, or 600N. Known methods may be used to
achieve and control the above forces, one example being a pneumatic actuator and one or more force
limiting mechanical actuators.
In one embodiment, the at least one stripping member or a part thereof may have a V-shape. In this
embodiment, the sharp end of the V pierces the intercostal tissue and the stripping member or part
thereof is inserted into the intercostal tissue until the opposing sides of the V-shape member abut or are
about the bone sides.
A single V-shape member may be used as the at least one stripping member, the meat cut in this
embodiment being Frenched bone by bone. The stripping member may instead comprise multiple V-
shape teeth all retained together in a common alignment. By taking this approach, multiple bones may
be stripped at once, with multiple V-shape teeth piercing the intercostal meat between different bones
and then stripping being completed of one or all of the pierced sections in a single drawing motion. The
common alignment noted may be achieved through use of a comb shape with a common base and V-
shape teeth protruding from the common base. V-shape teeth may be useful as they effectively self
align the bones – bones can have a varying position inside the intercostal tissue and by having the V-
shape teeth sides abut or lie about the bone edges, bone movement may be minimised relative to the
stripping member(s). In addition, should tissue removal be completed in a step manner i.e. one set of
tissue and then the next, the bones may move once their neighbour bone is free of intercostal tissue.
The V-shape teeth minimise bone movement even when a neighbouring intercostal tissue may have
been removed.
The at least one stripping member may instead be formed as two opposing either single or multiple V-
shape teeth. The opposing V-shape teeth may interlock about or around the same or alternating bones.
This style of stripping member may be useful to enhance the interference between the intercostal tissue
and stripping members. Opposing sided stripping members may also be useful to balance the drawing
force on the meat thereby providing a consistent force load thereby avoiding a rotational or torque force
during drawing.
The at least one stripping member may, as noted above, use multiple V-shape teeth. Aligned or
opposing V-shape teeth may overlap or otherwise mate together to have a scissor-like action optionally
engaging around at least part of the bone circumference. The mating action may be biased to urge the
V-shape teeth apart thereby spreading the bone or bones during the drawing process so that an even
strip is achieved. During the piercing step, the V-shape teeth may be moved against the bias action to a
neutral or closer aligned location and, once pierced, the bias action may be engaged to urge the V-shape
teeth apart and against the bone or bones.
The device and methods described may be partly or fully automated. For example, the striping member
or members may be integrated into an arm or arms that automatically detect and engage with a meat
cut or cuts moving on a conveyer. Alternatively, in a semi-automated device, a person may load and/or
unload the meat cut or cuts from the retention means while stripping occurs automatically.
The parts described above, including the retention means and stripping member or members, may in
part or in full be manufactured from steel or aluminium. The materials used may be food grade. One
particular material may be stainless steel although other food grade materials with sufficient structural
properties may also be used.
The parts may be sufficiently strong to not flex or distort in shape during operation. It may be useful to
ensure that the V-shape teeth if used are sufficiently rigid as to not blend or distort during stripping.
The device and methods described above may be completed without the need for sensing equipment or
controllers/processors. As may be appreciated, this simplifies the device and method and may also
reduce the cost and complexity of the device and method. Despite this, sensors could for example be
used to detect the mid point of the intercostal tissue between bones and this sensed output
manipulated in a processor that then provides a calculated output to the stripping member or members.
Sensors, controllers and/or processors may be used optionally to add accuracy or enhanced information
about the device and its operation. More details on potential sensing, controlling and processing
equipment is described in the applicant’s patent NZ585855 incorporated herein by reference however
the examples described should not be seen as limiting.
Advantages of the above based on the inventors work comprises:
Avoidance or minimisation of the need for manual labour ;
Increased safety to workers by minimising contact between the operator and moving parts or
sharp edges;
Avoidance of the need for additional potentially contaminating stripping action;
Potentially complete avoidance of the need for complex sensing and processing equipment;
The ability to French one or more multiple bones in a single stripping action;
The ability to at least partially automate the Frenching process;
The ability to more cleanly and consistently remove intercostal tissue than art devices.
The embodiments described above may also be said broadly to consist in the parts, elements and
features referred to or indicated in the specification of the application, individually or collectively, and
any or all combinations of any two or more said parts, elements or features.
Further, where specific integers are mentioned herein which have known equivalents in the art to which
the embodiments relate, such known equivalents are deemed to be incorporated herein as of
individually set forth.
WORKING EXAMPLES
The above described Frenching device and method of use are now described by reference to specific
examples.
EXAMPLE 1
The inventors constructed a scissor style device 1 that clamped around individual ribs 2 and stripped the
intercostal tissue 3 (see Figures 1 and 2). Figure 1 shows the scissor style device 1 and Figure 2 shows
the same device 1a interposed with a second device 1b opposing the first device 1a. The result is a
stripping member 1 that pierces the intercostal tissue 3 via sharp endings 4 and, as each ending 4 is
inserted further into the tissue 3, the V-shape 5 of the scissor 1 surrounds the rib bone 2 until the sides 6
of the V-shape 5 abut or lie about the bone 2 side. When the scissor style device 1 is drawn away
towards the bone 2 ending, the intercostal tissue 3 is stripped from the bone 2 by interference. The
scissor type device 1 shown in Figure 1 may be biased (not shown) to an open position, the open position
shown in Figure 1. During insertion into the intercostal tissue 3, the scissor endings 4 may be squeezed
together against the bias and then released once in position so the bias action urges the scissor endings
4 against or about the bones 2. The way the scissor style device 1 surrounds the rib bone 2, especially
when interposed with an opposing side scissor style device 1 provides a strong and tight fit around the
bone 2 thereby increasing the interference between the device 1 and tissue 3. In trials completed by the
inventors, the final stripped produced gave an excellent result as shown in Figure 2.
EXAMPLE 2
A further device 10 was manufactured as shown in Figure 3 and Figure 4. The device 10 in this Example
strips all of the rib bones 20 on a meat cut 30 at once as opposed to one bone 20 at a time as in
Example 1. The device 10 uses two opposing rigid combs 40a, 40b best seen in Figure 4. The combs 40a,
40b comprise a series of V-shape teeth 50 linked together via a common base 60. The combs 40a, 40b
also comprise a fold 70 about the common base 60 that is used to apply an even force across all of the
teeth 50. The comb 40a, 40b is manufactured from aluminium in the example shown, being 2mm thick
aluminium although other materials and material thicknesses may be used. The inventors found that it
was useful to have a thickness sufficient to avoid deformation or bending of the comb 40a, 40b or parts
thereof during the stripping process to ensure the best end result.
The test 70 rig used includes a retention means 80 in the form of two opposing rigid bars one fixed and
one removable clamped about the rib bones 20 at a point above the beginning point of tissue removal.
The V-shape teeth 50 on the combs 40a, 40b pierce the intercostal meat 90 about the centre of the
intercostal portion 90 and are meshed together so they overlap around the bones 20. Once in position,
the combs 40a, 40b are drawn towards the end of the bones 20 stripping the intercostal tissue 90 away
from the bones 20. Figure 5 illustrates the meat cut 30 post stripping where it can be seen that the
intercostal tissue 90 has been cleanly removed from the bones 20.
Aspects of the Frenching device and method of use have been described by way of example only and it
should be appreciated that modifications and additions may be made thereto without departing from
the scope of the claims herein.
